# ARDUINO

- [Arduino Backpack](https://lessons.mistyrobotics.com/arduino/arduino-backpack.md): You can use the Arduino-compatible backpack with sensors and other hardware to extend the capabilities of Misty's native hardware.
- [Arduino](https://lessons.mistyrobotics.com/arduino/arduino.md): You can create amazing project with Misty and Arduino even without the Arduino Backpack!
- [Arduino Lessons](https://lessons.mistyrobotics.com/arduino/arduino-lessons.md): The key to communication between Misty and Arduino is to properly control the different messages that they are writing to each other.
- [Arduino to Misty](https://lessons.mistyrobotics.com/arduino/arduino-lessons/arduino-to-misty.md): In this project, you will use Arduino to trigger Misty to change the colour of her chest LED.
- [Misty to Arduino](https://lessons.mistyrobotics.com/arduino/arduino-lessons/misty-to-arduino.md): In this project, you’ll use MIsty’s bump sensor to trigger Arduino to change its LEDs.
