Take this Christmas tree for example, which uses a 555 timer and a CB4017 decade counter in order to drive some blinking LEDs. The ICs are through-hole, making the circuit fairly accessible to new ...

The circuit works due to the fact that voltage increases or decreases linearly when a constant current flows into or out of a capacitor. If we manage to charge and discharge the capacitor with the ...

Bill decided to roll out his own rather than buy a pre-made tail light flasher so he grabbed a trusty 555 timer and started soldering. His circuit flashes the tail light a specific number of times ...
