could be used but I found no simple circuits. My first thought was just to connect a series current limiting resistor and LED to the cathode so that the LED would light when the reference ...

The first video is a simple circuit with ... features the same resistor/switches/LEDs, this time in a parallel circuit. Turning on the first switch makes the first LED light up, and the second ...

It allows both polarities to control the motor — however if you do it with just plain old switches or relays, you could short the circuit if you try going in both directions at once!

R 1 limits the base current of Q 1 when S 1 is closed. S 1 can be a manual switch, a relay contact, an optocoupler, or a transistor. If you close S 1, Q 1 turns on, and the motor runs. Figure 1 This ...

Older designs relied on simple resistors to limit LED drive current, but designing an LED circuit based on the typical forward ... Figure 1 illustrates a coordinated protection scheme for switch-mode ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly ...
