Heart Lamp with Flashes 18 LEDs Circuit
This activity flashes 18 LEDs at three altered ante and you can use these to actualize an clear Valentine Heart. The ambit is kept simple (and low cost) by application the 4060B IC which is a adverse and oscillator (clock) in one package. The ambit requires a 9V supply, such as a PP3 battery. It will not assignment with lower voltages and a college voltage will abort the LEDs.
The preset capricious resistor can be acclimated to acclimatize the oscillator abundance and this determines the beam amount of the LEDs. The IC banned the accepted to and from its outputs so the LEDs can be cautiously affiliated after resistors in alternation to absolute the current. The stripboard allotment of the ambit is accessible to body but the base for the LEDs needs affliction so abundant instructions are provided below.
