First Steps with the NodeMCU ESP8266 Wi-Fi Module

Click image, please, to enlarge.

In our previous tutorials we were using already the NodeMCU ESP8266 Wi-Fi Module and we discussed about “Security“, “Cyber-Security” issues while using “IoT“, “Internet of Things” and the importance that the router MUST be protected by a NEW password and NOT ALLOW to let connect any devices to our router/internet, unless we decide to let them (ONLY our owns) connect!

Please check again the tutorials below:

• First Steps with the ESP8266 Wi-Fi Module | Maker, MakerED, Coding | Scrolling Text (Time, Temp., Humidity…) with 8×8 LED MATRIX
• …

It was a bit a difficult procedure to find out the “MAC Address” of the NodeMCU ESP8266 Wi-Fi Module, isn’t it?! Well there is a more easy way to find out with a little Sketch.

Please check the tutorial and copy the Sketch from:

• https://techtutorialsx.com/2017/04/09/esp8266-get-mac-address/
• …

Now it is much more easy to run a project with a NodeMCU ESP8266 Wi-Fi Module. Connect your module to the computer through the USB cable,  chose the board in the Arduino IDE and upload the sketch. Check below the how-to, please.

Please check again (I don’t want to reinvent the wheel…) the tutorial below who explains very well in detail:

• https://techtutorialsx.com/2017/04/09/esp8266-get-mac-address/…
• …

Once having the “MAC Address” of our NodeMCU ESP8266 Wi-Fi Module we can now easily incorporate it into the allowed devices in our router.

.

NOW, click on the button “Add Wireless Device” as shown in above image.

A new window opens where you can add the new devices “MAC Address” which you wrote down before. Do so please and then click the button “OK“. Go back and have a look if the device is now in the authorized devices in your Network.

SO, now when you use a Sketch with “IoT” with the NodeMCU ESP8266 Wi-Fi Module, the device is recognized and allowed in your Network!
