Recently inherited a friend's "junk box". Found an unused AT-Mini board from Mikroelectronika, decided to give it a try. Seemed to flash in the Arudino IDE as a Due 328 board.
Turning a pair of pumps on and off works fine. Also Measuring temperature of fluid flow with an LM35 sensor, baud = 9600 and using the Arduino IDE to monitor ... strange problem
PROBLEM: the monitor must be set to 4800 else jiberish is printed. I tried this sketch on a Due and it printed to the monitor at 9600 baud so it must be something to do with the AT-Mini board. Thought I'd try here for understanding before swapping out to the Due.
FYI, control is via transistor switching of low current pump motors following http://www.instructables.com/id/Use-Arduino-with-TIP120-transistor-to-control-moto/.
