Learn: how light sensor works, how to connect light sensor to Arduino, how to code for light sensor, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you
Example - Analog Keypad Example - Analog Button ArrayArduino - Light Sensor Triggers LEDIn this tutorial, We are going to learn how to:If the light sensor's analog value is lower than a threshold, turn LED on If the light sensor's analog value is greater than a threshold, turn LED off...
Once we have the value, we compare and turn on the relevant LED. For example, the red LED will be on when it’s dark, yellow for shady and finally green for light. After this, we delay for 200ms and turn all the LEDs to low and check again. ...
Example of BH1750 library usage. This example initialises the BH1750 object using the default high resolution continuous mode and then makes a light level reading every second. */#include<Wire.h>#include<BH1750.h>BH1750 lightMeter;voidsetup(){Serial.begin(9600);// Initialize the I2C bus (...
intUVOUT = A0;//Output from the sensor intREF_3V3 = A1;//3.3V power on the Arduino board voidsetup(){ Serial.begin(9600); pinMode(UVOUT, INPUT); pinMode(REF_3V3, INPUT); Serial.println("MP8511 example"); } voidloop(){
An example of a larger switch is a transistor.Don’t draw more than 20 milliamps (mA) of current from your Arduino’s GPIO pins, otherwise you may damage it. Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor, relay (this is ...

Links back to the original library are included in the header for each example. A few categories have dedicated pages: Accelerometers Force Sensing Potentiometers Joystick Light Sensors Spectral Sensors MPX2102 Pressure Sensor PIR sensorAbout A collection of examples on how to interface sensors to ...
This example shows how to use the tone() command to generate a pitch that follows the values of an analog input. Using a photoresistor your Arduino board becomes a simplified light theremin. 本例展示使用音调 tone 命令来生成一段声音,声音由模拟输入决定。使用光敏电阻后 Arduino 板子就变成了一个...
