In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

Abstract: This article presents the Hall-sensor-based magnetic force modeling and inverse modeling for the hexapole electromagnetic actuation. Whereas mathematical models are derived for a specific ...

Allegro MicroSystems is introducing the ACS37017, a Hall effect current sensor targeting power converters, EVs, industrial motor control and clean energy systems. The device integrates a stable, ...

Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in a compact PSOF package for high-voltage systems. How the ACS37200’s 50-µΩ ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

This tutorial covers how to build a practical and expandable Villager Trading Hall in Minecraft 1.21+, compatible with both Java and Bedrock editions. Ideal for survival gameplay, the design supports ...

Diodes’ AH4930Q sensor detects magnetic fields along the X, Y, and Z axes for contactless rotary motion and proximity sensing. As the company’s first automotive-compliant 3D linear Hall effect sensor, ...

After improving hard drives, tunneling magnetoresistance technology could put an end to joystick drift. After improving hard drives, tunneling magnetoresistance technology could put an end to ...

PLANO, Texas--(BUSINESS WIRE)--Diodes Incorporated (Diodes) (Nasdaq: DIOD) today introduces its first series of advanced InSb Hall element sensors for rotation speed detection and current measurement ...

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 ended up using a microcontroller and a piece ...
