My UNO board is displaying on a TV flat screen (using TVout via RCA cable). I have 60 analog inputs going into 12 analog pins in the MICRO board (5 on each pin using resistors for voltage dividers). Each voltage value results in a string of characters. I need to get these inputs on a larger flat screen. Does anyone know a solution for this? Is there a way I can hook them both together so I can utilize the 12 analog inputs on the MICRO and just use the UNO for TVout?
Sure - Rx to Tx, Tx to Rx, Gnd to Gnd. Transfer away using Serial.write();
