For demonstration in the analog mode, we have connected an LED to the digital pin 6 of the Arduino and we will change the brightness of the LED depending upon the water droplets on top of the sensor.

Now as per the code i have written that when the object is at 25cm away from the sensor, glow the 7th LED . Than as the distance decreases the another LED's starts glowing as per the code. In the code ...

Arduino Sound Sensor Code. The Arduino Sound Sensor Code is very simple and easy to understand. We are just reading the analog data out of the sensor and lighting up LEDs to visualize the intensity of ...

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it … ...

Arduino codes for an Interactive Light Box using ultrasonic sensor, relay module and 12V LED stripe. Material: Scissors, Arduino Uno, relay module, ultrasonic sensor, breadboard, jumper wires, 12V LED ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can bu… ...
