automatic street light | seminar report, ppt, pdf for ece

aim of this seminar is to control the street light using ldr. when the light falling occur means resistance value will be change. there is no light then the resistance value is change. from this resistance change the voltage variation can be obtained this value is given to adc of pic.

automatic street light controller arduino project hub

when there is low amount of light the light automatically glows and when there is sufficient amount of light it automatically turns off the light. here based on our room condition the threshold value we took is 100 for the ldr sensor. when we place a hand on ldr(not allowing any light on ldr) arduino automatically turns on the led.
