Project Description: in this project, we used ldr sensor and made led activation device,
problem: maximum power consumption, need to be automated, activation accuracy
solution: with the help of arduino uno and it interfaced with ldr sensor, so we can overcome the all above problems,
when ldr sensor sense the darkness so ldr gives high signal to the board and it activates the led...
application,: street light, room automated dim light, parking area, front and backyard,
advantages: it decrees power consumption, it decrees accidents, high accuracy, automated,
