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 ...

While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

With over 20 unique sensor types, and the ability to be used with several different development platforms, Tarts wireless sensors allow for endless sensing, monitoring and control possibilities.

Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs.

Current sensor rejects PWM for motor control Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ...
