Single Transistor LED Flasher Circuit
It is possibly the smallest LED flasher to date, which is able to flash an LED ON/OFF infinitely using a single transistor, a resistor, and a capacitor. Can you imagine making a great looking LED flasher or blinker with just a single transistor and a couple of other passive parts? That’s exactly what I have […]
