Photoresistor and an ATmega168 ADC

I’m starting on a new project and thought I’d share the first step. I eventually want to use two photoresistors to push data into the microcontroller. You’ve got to crawl before you can walk and I’ve...

Manchester encoding between monitor and light sensor

I’ve been working on a way to push data into a microcontroller using a computer monitor (or smart phone) which flashes black and white. I’ve done some preliminary tests using one photoresistor read by...
