This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Components used in the project listed: Arduino Uno R3 x1 Pushbutton x4 Potentiometer (10K Ohm) x1 LCD Display (16x2) x1 Piezo Buzzer x1 Temperature Sensor [TMP36] x1 Resistor (220 Ohm) x1 Resistor ...

The code sets up the LED as output and the sensor as input. Timer 1 is configured with a prescaler of 256 to generate interrupt for every 250 milliseconds. The interrupt service routine (ISR) toggles ...
