Capacitive Touch with Atmel’s AT42QT1070 Touch Sensor IC

Capacitive Touch with Atmel’s AT42QT1070 Touch Sensor IC

Leave a Comment / Using Atmega / By

Rather than using an out-of-the-box capacitive touch solution for my projects, I thought I’d attempt making my own little breakout board. The idea is to use a sensor capable of triggering normal digital input pins using touch. This post covers the selected touch sensor IC, the circuit used, getting a custom PCB made and how …

AVR-based Sensor Keyboard Using Atmega

Leave a Comment / Using Atmega / By

A modern microcontroller has almost everything that’s needed to implement a touch sensor matrix. There are several sensing technologies: IC manufacturers typically advise using certain tech, sometimes they offer ready to use hardware- or software-based solutions. I was curious to try to implement a sensor matrix entirely from scratch all by myself. Here’s how it …

UV Sensor ML8511 AVR Atmega library

Leave a Comment / Using Atmega / By

Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm. The ML8511 is an ultraviolet sensor that output an analog signal correlated to the amount of UV light detected. By datasheet the sensor detects wavelength from 280nm to 560nm. Here I’ve implemented a driver for AVR Atmega, portable to other microcontrollers, that correlates the sensor output …
