Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...
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 ...
Light Source and Objects Proximity Detector System – the project structured as a finite state machine. The system comprises several states: The MSP430FG4619 MCU comes with two Timers, TimerA and ...
