Automatic-headlamp-control-using-arduino, the lamp. then prepare the lamp to be hooked up to the wall plug and the relay one terminal will be connected directly to the plug, the other one will have a cut in the middle of the way, one end of the cut will go to the normally open pin (no1 ) in the relay module, the other one will go to the com1 pin and then the plug.. How the ldr operates. light falling over the ldr from the headlight of the vehicle coming from the front instantly lowers its resistance and allows more current to flow to the base of the transistor.. the transistor conducts and activates the relay, which in turn flips the contacts such that the host vehicle's headlamps gets connected with the dipper filament, changing its intensity., international journal of engineering and applied sciences (ijeas) issn: 2394-3661, volume-2, issue-8, august 2015 107 www.ijeas.org.
Here is a simple automatic car headlight,this means when get darker the circuit gonna activate ur car head light automatically ,and switch them off when ligh..., automatic headlight switcher. basically, an ldr is a resistor whose resistance decreases with increase in the intensity of the incident light. usually, an ldr exhibits very high resistance in darkness and low resistance in the presence of ambient light. thus a varying voltage drop can be obtained across it with changing ambient light conditions..
