The traditional theremin is more or less an audio oscillator with two metal rods. Using proximity sensing, one rod controls the pitch of the oscillator and the other controls the volume. [Teodor Co… ...

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 ...

A proximity sensor detects the ball and starts up a pair of 540 R/C motors, ... Posted in Tool Hacks Tagged arduino, proximity sensor, router, VCNL4020, woodworking. Gesture Based Security Lock.

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

It’s called Speaker Proximity, and it allows your phone to automatically toggle between speaker and ear piece during a call by using your phone’s proximity sensor.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
