LED control scheme with LDR prepared with Proteus Programm. Write code in Arduino. Question If Light intensity is less than 100 LED will turn on 1000 If higher than -100, the LED will turn off, write arduino code. If led turn off write Led Status:1 else Led Status: 0 - When the value is 100, the value you read from the analog input will be your threshold value. No calculation needed. -No need to adjust the Brightness of the LED. Only the led will turn on or off. -Virtual machine screen output For example LDR value: 835 , LED Status:1 LDR value : 825 LED Status:1 LDR value: 823 LED Status:0 LDR value: 823 , LED Status: 0 Arduino Scheme LED BLUE - ODLO ON des www.TheEngineering Projects.com AINARA!
