This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

We used Ultrasonic sensor in many of our application to measure the distance: Arduino & Ultrasonic Sensor Based Distance Measurement; Measure Distance using Raspberry Pi and HCSR04 Ultrasonic Sensor; ...

Ultrasonic Sensor Module. There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm.The sensor ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Arduino driver for the PAA5100JE and Pixart PMW3901(not tested atm) optical flow sensors. The driver was originally developed to support the Bitcraze Flow Breakout board. It communicates with the ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.
