solar outdoor lighting is a great way to help reduce your energy usage. solar powered light fixtures collect energy during the day then switch on while it's dark. they are a great option for lining pathways and steps, or around gardens and flowerbeds.
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.

sep 18, 2017 here in this project we are going to make a simple automatic street light controller using relay and ldr. this circuit is simple and can be built with transistors and ldr, you don t need any op amp or 555 ic to trigger the ac load.
a charge controller, or charge regulator, is basically a voltage and/or current regulator to keep batteries from overcharging. it regulates the voltage and current coming from the solar panels going to the battery. most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.
