This circuit enables any infrared (IR) remote control to control the outputs of a 4017 decade counter. It’s quite simple really and uses a 3-terminal IR receiver (IRD1) to pick up infrared signals ...

This novel circuit uses a flashing LED as the clock input for a 4017 decade counter. Typical flashing LEDs (eg, DSE cat Z-4044) flash at about 2Hz so the outputs Q0-Q9 will cycle through at that rate.
