Make an ATTiny85 Laser LED Sign
Today we are going to make a Laser LED Sign with a custom ATTiny85 PCB and laser cut base.
I go step by step through the PCB construction, all the way to programming the ATTiny85 chip.
Why did I use a custom ATTiny85 PCB instead of an Arduino nano? Well I wanted something super small and I only needed 1 GPIO + I had a bunch sitting in a drawer and they were getting lonely ;)
The hardware I use to program the ATTiny85 chip is based on Brian Lough's ATTiny85 DIY Programer video...
