Story I am working on a project which requires reading multiple sensor data on different locations. These require only few PWM pins so using multiple Arduino Uno would be expensive and unnecessary. So I decided to use ATtiny85 microcontroller in place of Arduino Uno development boards. ATtiny85 is a cheap and powerful alternate when u don't need too many PWM pins. Since ATtiny85 is just a microcontroller we ...

Your last two Arduino projects of the semester will deal with infrared communications.  This lab will prepare you for those projects.  In this lab, you will: build a circuit and code for sending infrared light, build a circuit and code for detecting infrared light, and work with a partner to experiment with IR communications. This lab is self-paced, but your instructor will be happy to help you with any que ...
