ATtiny 85 Continuity Tester
This was a great little project to use the Attiny 85 microcontroller that is very cheap and easy to work with. The purpose was to make this a little group project and have some fun soldering these little components together. Once COVID is over, can get the group together and build more.
Upon startup, both red & green lights will come to ensure they are working, if a short between the center pin & shield of your coax is detected the red light would come on & the green goes off. If no short detected then the green light stays on.
