Photosensitive Timing Infrared LED Control System with Ardui

Photosensitive Timing Infrared LED Control System Based On Arduino by www.ICStation.com
1) When start up, the hardware initialized and the LED will flash. The 4-bit digital tube display the initialized time 23:59.

2)When nobody appears in the infrared induction area, the LED will not light.

3)When the intensity of environmental light is weak and somebody is appearing in the infrared induction area, the LED will light till the person leaves the infrared induction area.

4) On 24 o’clock at midnight, the buzzer will alarm and the LED will switch to the manual control till 8 o’clock in the morning.

5)You can set the time by the switches.
