This project flashes 18 LEDs at three different rates and you can use these to create an eye-catching
Valentine Heart! The circuit is kept simple (and low cost) by using the 4060B IC which is a counter and
oscillator (clock) in one package. The circuit requires a 9V supply, such as a PP3 battery. It will not work
with lower voltages and a higher voltage will destroy the LEDs.
