Glove Controller with PIC32 and LCD

Digital “Etch A Sketch” Glove

Introduction For our ECE 4760 final project, we designed, constructed, and tested a glove-operated system that dynamically simulates the classic toy, Etch A Sketch, on a TFT LCD screen. In deciding what to build, our team wanted to create a device that would utilize several of the technologies overviewed in the course, in a fun, …

LOW-POWER BUTTON REPLACEMENT WITH FORCE-SENSITIVE RESISTOR

LOW-POWER BUTTON REPLACEMENT WITH FORCE-SENSITIVE RESISTOR

Introduction A common requirement for devices that must be sealed from environmental exposure is to replace all metal contact style push-buttons with functional replacements that do not have those weather-sealing difficulties. This article describes one such way of creating a contact button replacement using a Force-Sensitive Resistor (FSR) in conjunction with an SLG47004V. Design Description …

HALL EFFECT SWITCHES HAVE SELF-DIAGNOSTICS CAPABILITY

HALL EFFECT SWITCHES HAVE SELF-DIAGNOSTICS CAPABILITY

Diodes Incorporated has announced a family of automotive-compliant, two-wire unipolar (AH323xQ/4xQ) and latch (AH327xQ/8xQ) switch integrated circuits (ICs) that provide high sensitivity and high stability over wide operating voltage and temperature ranges. The ICs are for use in automotive proximity- and position-sensing applications, including seatbelt buckle, power window, gear selector and seat position. The adoption of two-wire hall switches reduces the …
