Sketch for a capacitive proximity / touch sensor with Arduino. This sensor based on a square wave generator rather than charge time measurement as the popular CapSense library. This design results in ...

Hook-up the electrodes to the MPR121 breakout board; Connect the Arduino to the MPR121 breakout board ###2. Software Set-up. Load the sketch on the Arduino; Open the serial port at 9600 bauds; ...

In this tutorial, we are going to interface E18-D80NK IR Proximity Sensor with Arduino. The E18-D80NK is an advanced low-cost IR Proximity Sensor with an obstacle detection range of 3 cm to 80 cm. The ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the… ...

IoT projects needing compact boards are often limited to boards with 10–100 I/O pins, laser modules, or without sensors. Coin V2 addresses these challenges with features like an accelerometer, ...

Rutronik Adapter Board RAB7 is an open-source hardware Arduino shield designed for AI-powered Sensor Fusion with seven environmental and inertial sensors from Bosch, Infineon, and Sensirion. The ...
