so the blinking only occurs in darkness. Of course, the resistor also has to have a sufficient view of the LED. You might use this as a safety light that only works in the dark. A simple circuit ...

Probably not, but here is what I tried: Flashing is legal these days ... as I couldn’t find a 4V3 Zener), the Zener pulls the transistor on and lights the leds. The 3n3 capacitor gives the circuit ...

Part 1: Light Touch Construct the first circuit using a single transistor, an LED, a power source, and a resistance. The brightness of the LED will indicate the relationship between the current ...

What [Manuka] gives us is a circuit that is designed to be built into your project or project’s power supply. Using only an ultra-bright white LED, red blinking LED, PNP transistor, and a diode ...
