Use an Android app to control the digital pins of your Arduino microcontroller through the ESP8266 WiFi module. The Android app will have three buttons that you can use to toggle three LEDs connected to your Arduino board. The Androi application sends an HTTP request to the ESP8266 and the Arduino processes the request.

Use the ESP8266 to control your Arduino’s pins via WiFi. In this tutorial we will create a webpage with three buttons to control LEDs connected to the Arduino from the internet.

The ESP8266 can easily be used as a webserver but you’ll need a microcontroller to handle the http events/requests. In this tutorial we’ll use the arduino to help the esp serve websites.

So you got the world wide famous ESP8266 wifi module to play around with it and your Arduino but don’t know where/how to get started? For starters, the ESP8266 requires a 3.3V input which we can get by connecting a 3.3V regulator to the Arduino’s Vin pin. The code is just as simple, a loop to receive and send commands, and another loop to print the response.

Learn to connect a PIC microcontroller to a 4-digit 7-segment LED display.

In this tutorial I will show you how to blink the RED led in your Stellaris LaunchPad board.

In this tutorial you will learn how to program your Stellaris LaunchPad to use the built in buttons to turn on the RGB led depending on the combination of switches you press.

The Arduino is not the only microcontroller that can connect to LabVIEW, some PIC18 microcontrollers also have that capability and the code is easy to write thanks to the MC18 USART library.
