ELEGOO SMART ROBOT CAR KIT V3.0

.


First impressions

Elegoo Smart Robot Car Kit for Arduino.

.

The Kit is delivered in a well organized plastic box with a poster inside of all the parts with description and a CD with the PDF Manual, Code and Libraries.

The manual in PDF format is actually very well documented an nobody should have problems to follow the instructions.

There are even the necessary tools for assembling provided, such as different screwdrivers.

.

 

.


Assembling and cabling

Assembling part 1.

.

.

.

First steps, assembling… Actually it isn’t that difficult, only problem encountered are 2mm screws and nuts, I will continue tomorrow with a magnifying glass and more light to handle it (OH my eyes…). There was some fight with screws and nuts ranging from 1.6mm (Ultrasonic Sensor) to 2mm (Servo fixing) where I needed to use special tools, was a bit stressing to work with such tiny things.

.

.

.

.

.

ToolsFor solving the problems encountered with the tiny screws and nuts, I used a “magnetic telescope” for the 1.6 mm nuts and a “spring-loaded tongs” for the 3 mm nuts.

The cabling was very easy and the rest of the assembling as well as it is VERY well described in the Assembling document (in PDF). Next step is to control (End-Control) again the cabling to make sure that everything is correctly connected and THEN the Coding

The documentation is available in different languages…

Charger with US plugWhen living in Europe, make sure to make your order on the national platform from Amazon, I made my order in the US and I got the charger delivered with an US plug! Amazon Germany delivers it with an “Euro Plug”! <===>

I made the End Control, checking if the connections were made right, it was.

 

.

Assembling part 2

.

Assembling the two black plates and the wheels was easy peasy as well…

The Coding

Manual on CD

Click the image, please, to enlarge.

Opening the Manual NOW to proceed for the first lesson “Make the car move on [Auto-GO]”. Very easy to follow, it worked in less than 5 minutes. Unplugging the USB cable from the laptop, will it work!?

Taking the car away from the desk and putting it on the floor, switching the Power-supply on and it runs around by avoiding any obstacles while they are detected by the “Ultrasonic Sensor”, it’s FUN watching <===> Success Trying out NEXT lesson now…

The courses are made very easy: plug the USB cable to the computer, open the course in the Arduino IDE, upload it into the IDE, save it in your folder, unplug the USB cable, take the car away from the desk and put it on the floor, switch it on and enjoying…

Well, that’s a Kit which everybody can try and have success, give it a try and enjoy “Coding”, “Maker” activities…

First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project

First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project

.

Temperature/Humidity Sensor DHT11 and LCD1602

.


Super Starter Kit UNO R3 Project | LCD and Sensors Project | Temperature/Humidity Sensor DHT11

SO, as I got my new Super Starter Kit UNO R3 Project I am playing around a bit with it. In my previous post WE were wiring and testing a LCD-Display and coding to display a bit text on the LCD. That was actually very easy, so lets try out now some “Sensors“, e.g. a Temperature/Humidity Sensor and a Ultrasonic Sensor to measure distances. The measured values of those sensors will get displayed on the LCD-Display.

Let us start first with the Temperature/Humidity Sensor DHT11 which is included in the Kit:

WE will use the following tutorial from Dejan Nedelkovski (How To Mechatronics) as it is very well documented and explained (no need for me to create a new one…). First we will check the video below, please, where we will get explained the How-To and some theoretical explications:

.

.

SO, now after knowing what will be necessary to do, we will first make the wiring of the LCD-Display, please check below:

.

LCD1602-Wiring with Arduino

Click the image above please to access the tutorial

.

As you can see in the above wiring diagram, there isn’t that much wiring to do. When following the tutorial <===> Arduino LCD Tutorial <===> you will get proposed some examples of code to play around with. Try them out to repeat the learned from previous blog post or just leave the wiring as it is to proceed to the next step, the wiring of the Temperature/Humidity Sensor DHT11.

We will continue to follow the tutorial <===> DHT11 & DHT22 Sensors Temperature and Humidity Tutorial using Arduino <===> where the Temperature/Humidity Sensor DHT22 is used. As we use DHT11, you need only to forget about the resistor as it is not needed, replace it by a connection cable (strip).

.

DHT22-Wiring Diagram

Click the above image please to access the tutorial

.

The wiring ready now, we go for the coding. The sketch is available here <===>  DHT11 & DHT22 Sensors Temperature and Humidity Tutorial using Arduino <===> Upload it into the Arduino IDE and give it a try. You will see the result as shown in the image below:

.

DHT22 Code for DHT11

.

There is something strange on the displayed values, isn’t!? WHAT happend!? Let us make some trouble-shooting: the wiring is OK, otherwise the wouldn’t be anything displayed, is the sensor defective!? If you have a second one, replace it to make sure. Same results again, hmmmm!? OK, it’s mysterious on some way, but there must be a solution for it… Let us check the sketch, the code, again to try to understand WHAT the Arduino is getting told to do and WHY the display shows something completely different, the problem is certainly then in the code. Let us review the video tutorial, perhaps we missed something (I did…). In the video, if really listened to, it get explained the two possibilities, using a sensor DHT11 or a DHT22. The code is written for a DHT22 sensor and we use a DHT11 sensor; so WHAT to change now in the code!? Please check the screenshot of the sketch below:

.

Sketch-DHT22-Arduino

Click the image please to enlarge it

.

Once change that code line upload it to the Arduino IDE and see WHAT happens on the LCD-Screen. See PIC below please.

.

Temperature/Humidity Sensor DHT11 and LCD1602

.

Well, that’s success!! It works correctly now 😉 Play around with it to see the difference on the LCD-Display while blowing on the sensor. Give it a bit time that the measured values go back again to the previous shown one. SO, as we had now a positive experience and where we can see WHAT is happening on the LCD-Display, let us try another project, we will measure distances with the Ultrasonic-Sensor. But befor we ared going for a NEW project we need to save our project, check the video tutorial below please.

.

 


Super Starter Kit UNO R3 Project | LCD and Sensors Project | Ultrasonic Sensor HC-SR04

We will keep exactly the same wiring diagram for the LCD-Display and taking away the Temperature/Humidity sensor with its wires from the Breadboard. Then we will have a look on the following tutorial, we will use the tutorial from  Dejan Nedelkovski (How To Mechatronics) again, check please <===> http://howtomechatronics.com/tutorials/arduino/ultrasonic-sensor-hc-sr04/ <===> as the previous one was working well! SO, remember that you have to remove the DHT11 Sensor and the wires from it to the Arduino board and follow the next wiring diagram, please. First we will watch the video tutorial.

.

.

Here below the wiring diagram.

ULTRASONIC-HC-SR04-Wiring diagram-LCD-Display

Click the image please to access the tutorial

.

Next step is to load the code, follow <===> If you want to display the results from the HC-SR04 Ultrasonic Sensor on an LCD you can use the following source code from <===> http://howtomechatronics.com/tutorials/arduino/ultrasonic-sensor-hc-sr04/ <===> and to upload it to the Arduino IDE. That’s it folks, check below please to see the result!

.

ULTRASONIC SENSOR-HC-SR04-and LCD-DISPLAY

.

It works up from the beginning, a success experience! Well folks, as you see it isn’t that much difficult to play around with the Arduino and Coding; don’t forget to save your project so that you can use it again if once needed and try out other projects as well, check the <===> Elegoo UNO R3 Project Super Starter Kit <===> PDF download to GO for NEW LEARNing-By-Doing adventures 😉

Super Starter Kit UNO R3 Project From Elegoo

Elegoo Super Starter-Kit Project Arduino UNO R3In one of my previous blog posts I used Arduino-UNO Starter Kit, which I ordered at Conrad (English version) and I wasn’t really impressed by the manual, it didn’t satisfy to my expectations and needs. SO, I was looking around to find some distributors for a BETTER version… At “Amazon US” I found Elegoo UNO Project Super Starter Kit with Tutorial for Arduino. First of all, the kit is delivered in a plastic box and its price is also attractive, $34.99.

The manual with the code, libraries and tutorials is on a DVD. So, I was looking first on the DVD and reading the Manual in PDF format to see the quality of the tutorials and the tutorials in PDF are very well documented. Once knowing WHAT is possible to do I made my choice for the “LCD-Tutorial“…

Below is the “Wiring diagram“, the How-To to connect the wires to make it work.

.

LCD-Wiring Diagram

.

As yo can see, it isn’t that much to do. Once the wiring ready, it is time to upload the code to the IDE and make it run to the success 😉 With the delivered code you will see the message “Hello World” on the LCD-Display.

.

Hello World-LCD-Display

.

Here below the code where the message “Hello World” is in.

.

Hello World-LCD-Display-Code

 

SO, why not playing around a bit to understand the code and changing the text message in <===> lcd.print(“Hello, World!”); <===> into something different, something more personal!? That’s WHAT I did, here my code change:


lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print(“Gust MEES – LCD”);


which shows up as, see image below please.

.

Arduino-Change of code for LCD-Display

.

The LCD-Display shows now my name as well (photo was taken when the counter was at 62) as my age, yes I am 62 years old (actually young, LOL); meaning that WHEN I can do this you for sure are able to do it! SO, WHAT are you waiting for to START learning about coding!!?

Reflecting for ideas:

SO, WHY not assembling everything into a box and use it as your personal “Door Name Display“, play around with some text and find out…

Ready, START, GO… Have fun by LEARNing-By-Doing 😉
