value = map(value, 0, 1023, 0, 255); Then, using this value, the LED bulb is turned on and off. analogWrite(led, value); With this code, the amount of light in the bulb increases or decreases depending on the amount of light received by the sensor. Look at the code below. This...
Learn how a LDR light sensor module works, how to connect the LDR light sensor module to Arduino, how to program Arduino to detect the light. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help
Arduino UNO Board Arduino UNO is a microcontroller board, contains an on-board power supply, USB port to communicate with PC, and an Atmel microcontroller chip. It simplifies the process of creating any control system by providing the standard board that can be programmed and connected to the s...
The Arduino board will give us an analog value between 0 and 1023 on the A0 pin. When there is no light, the analog value will be lower, and when the intensity of light is higher, the analog value will be higher. We have set a threshold value in the code, which is 500. So, whe...

Once you’re done simply upload it to the Arduino and your circuit should come to life. You may need to tinker with the values inside the if statements as this can vary depending on your lighting conditions. Troubleshooting Now if you’re finding things aren’t working exactly as you would...
Green House Monitoring Using Arduino In today’s greenhouses, many parameter measurements are required to monitor and control for the good quality and productivity of plants. But to get the desired results there are some very important factors which come into play like Temperature, Humidity, Light...
