for use with NXP LPC1768 Microcontroller mbed application board. The programme Reads the LM75B sensor temperature and Pot1 analogue input as room temp and thermostat temp setting respectively. Displays the temp and thermostat readings on LCD display and switches LED 1,2 and 4 on and off to indicated too hot, too cold and heater on or off.
