This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

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. The nRF52840 ...

To sense high dc currents, designers typically use shunt resistors or Hall-Effect-based current sensors. But shunt resistors are plagued by Joule (I2R) losses and the need to open the circuit where ...

Anyone who’s ever tried their hand at reverse engineering a piece of hardware has wished there was some kind of magic wand you could tap on a PCB to understand what its doing and why. We imagine ...

Capacitive sensing isn't limited to your smartphone. In fact, you can use contact with human skin (or any other conductive surface) to trigger almost any circuit. And the Touch Board from Bare ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...
