Temperature/Humidity on OLED Display | THE Breakout

In a previous tutorial WE have seen the Grove Beginner Kit for Arduino from SEEEDSTUDIO https://gustmees.wordpress.com/2020/08/03/grove-beginner-kit-for-arduino-seeedstudio-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/, now WE make THE BREAKOUT to use the different modules with OWN Code examples.

You can also take the modules out and use Grove cables to connect the modules. To do so, you need a sharp cutter, see PIC, please.

.

.

My recommendation for sharp cutters, which I use as well:

.

 

.

Once cut out you have made the BREAKOUT and in this case the two modules “OLED Display 0.96 inch” and “Temperature/Humidity” modules are ready to get connected to the main module. NOW we have to connect them through the delivered connection cables. Here below a picture:

.

.

As you can see, the OLED-Module is connected to the I2C connector, while the “Temperature/Humidity-Module” is connected to the “D3” connector. See PIC below, please:

.

.

SO WHY the “D3” connector for the “Temperature/Humidity-Module”?! Well, let us have a look on the code:

.

.

As you can see in this shown part of the code, there is marked ===> “#define DHTPIN 3“, SO it should GET connected to the “D3-connector” on the main board! If you use “D4” or whatever connector, SO you should change the code from “3” to “4” and so on!!! Give it a try and play around with it for understanding 😉

.


Temperature/Humidity on OLED Display | THE Code

Well, the two connections with the provided cables with connectors took ONLY a few seconds, ISN’T it? 😉 Let’s GO now to upload the code. Open your “Arduino IDE“, click on “NEW“, erase the few lines marked in there, make a “Copy&Paste” from the mentioned Code below and paste it in the “Arduino IDE (NEW)” and upload it, here below the code:

.

.

As you can see there is a “special” indication on the display, THE “Heat Index“, WHAT is it?! I encourage you to read my following tutorial which explains:

 

Have fun learning with PracTICE and stay tuned for next adventures of learning 😉

First Steps with the Arduino-UNO and NANO | Maker, MakerED, MakerSpaces, Coding | Temperature & Humidity monitor using Arduino NANO + DHT22 + 0.96 inch 128X64 I2C OLED

Temperature & Humidity monitor using Arduino NANO + DHT22 + 0.96 inch 128X64 I2C OLED

WE were playing around a lot already with I2C-LCD displays <===> https://gustmees.wordpress.com/?s=i2c+lcd <===> but not yet with I2C-OLEDs. In this tutorial WE will create a <===> Temperature & Humidity monitor using Arduino NANO + DHT22 + 0.96 inch 128X64 I2C OLED <===> which displays the temperature in °F AND °C, as well as it displays the “Heat Index“.

FIRST of all, let us talk about the Heat Index“, what it is and WHY it could be important to display it:

NO more Theory now, the PracTICE!

Let us have a look on the wiring and check the below Fritzing, please. It shows a DHT11 Sensor instead of a DHT22 Sensor, but the wiring is the same. It shows ALSO a 220 Ohm resistor instead of a 10K resistor!! Use a 10K resistor please!!

.

.

Once finished the wiring, WE will need to go for the coding by using a Sketch, we will use a already done Sketch, which WE can transform to our needs from:

IF you use “°Fahrenheit” you can use it without any changes, but IF you use “°Celsius” in your country WE will need to make some changes in the code, which WE will discuss the How-To here below.

First step: you can change the text, IF wanted: Original says "DHTxx test!", I changed it to what you see below; GET creative ;)

SO, here below the changes to make to display in “°Celsius“:

.

 

You might need to add certain libraries, see below please which ones will GET needed, please.

.

.

 

IF a newbie, please check the below tutorial for the How-To:

.

Well, that ISN’T difficult folks 😉

.


Check the video below, please, to see it in action (Fahrenheit version).
