Light dependent LED switch

A simple circuit that lights up a led when the LDR gets light. I use it as a tally extension for Blackmagic Camera Converters with the LED on the end of a cable. The 5k resistor is in reality a Light Dependant Resistor (LDR) that changes between 5k ohm and 1M ohm depending on how much light it receives. More light = lower resistance.

Instead of a LDR you can use a LED. Look at my Circuits
