You’re asking what is LDR? It stands for Light Dependent Resistor or Photoresistor, which is a passive electronic component, basically a resistor which has a resistance that varies depending of the ...

Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more than ...

This is a very interesting a.c. voltage stabilizer that uses a LDR or photoresistor to stabilize an alternating current (AC). If the voltage increases then the brightness of the light bulb increases ...

[john] sent in his version of a power meter monitor. It’s designed to monitor the blinking light on the meter to monitor the current power usage. The light flashes in proportion to the amount of power ...
