We are going to blink the LED at half a second rate. As shown in the above circuit diagram for interfacing LED with AVR microcontroller, there is no need to connect an external crystal here. Because ...

This project demonstrates how to control an LED connected to an ESP8266 using the Blynk 2.0 IoT platform ... Copy the Auth Token provided by Blynk and replace it in the code. Modify the code: Replace ...

To run this code, I used the PlatformIO for VSCode. The ESP8266 I am using is the Lolin NodeMCU v3 board ... There are two independent codes within this function, one to just make the led blink on and ...

This LED can be replaced by a Relay and an AC appliance to build a Home Automation Application. Circuit diagram to connect Bluetooth module HC-05 with NodeMCU ESP8266 is very simple ... The default ...

For those following along at home, [WhisleyTangoHotel] provides a hand-drawn diagram ... code. Interestingly enough, in the past we’ve seen a single LED clock that didn’t use Morse code to ...
