Dr. Paul Buckley counts sheep to stay awake and accurate in his small farm in Scarborough. His scanner uses a Raspberry Pi and and and Adafruit 16×2 display! via MagPi
“I found, to my surprise and delight, that numbers appeared on the screen when I wafted an old sheep tag over the aerial of the reader module,” recalls Paul. “My wife failed to see why I was excited. I persevered and learnt how to manipulate the data string to produce CSV-compatible output, and then how to create and append it to a text file on the SD card.”
