Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed.

Connect analog light sensor to A0 pin on your Arduino and upload ArduinoAutoBrightnessSketch.ino on it. Ensure that Arduino sends information to your PC using "Port monitor" on Arduino IDE or similar ...

Analog sensors output a variable voltage and resistance as they are activated. The most generic type of analog sensor is a potentiometer, and more specific types include flex sensors, photoresistors, ...

今回のプロジェクトでは、圧電スピーカーを使いますが、センサーとして使います。Arduinoのアナログ入力端子につなげば、振動を読み取るセンサーになるのです。 圧電スピーカーの上の部分をトンとたたくと、Arduinoはこのノックしたときの振動の強さを読み取ります。 3色のLEDを使用しますが ...

Arduino Hall Effect Sensor Working: Once you are ready with your Hardware and Code, just upload the Code to the Arduino. I have used a 9V battery to power the whole set-up you can use any preferable ...

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...
