Programming the SMALLEST Chip I’ve Ever Used

In this video, we explore the ATTiny45 and how to program it using the Arduino as a programmer. The ATTiny45 is a small chip with a ton of power to shrink-ify your Arduino projects. This AVR chip packs a punch! Here, we learn how to program the ATTiny45 and write a basic program in baremetal C on the device to allow us to make small, efficient code. Writing code for smaller chips like the ATTiny is a lot of fun!
