Here is the circuit diagram of Two Flashing LED’s for different applications (such as model construction), and recreational. Having adjustable flashing speed with two potentiometers. It is the ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

HB (high-brightness) LEDs require a large amount of current to operate. When driving HB LEDs from a voltage source, you can set the required current with a suitable series resistor. If the voltage ...
