Tutorial for writing better C++ code to control an LED with an Arduino The BlinkLED example code shows how to blink one or more LEDs. There are multiple versions of the code, showing better and better ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

The LED is connected to pin GPIO2 of the ESP-01 module through a 330 ohm resistor. The ESP-01 module needs a 3.3V supply. Arduino code for ESP8266 module: ...

Here we are going to write a program to blink an LED for every 500ms. In arduino uno, a LED will be already designed at the pin13, but we are not going to use it. Here we are going to connect an ...
