After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

The sensor is analog and gives analog output. I don’t know much about these flip-stick-click-lipstick, but I think it can be done using PWM rather MIDI to be more like theremin than auto-tuned ...

Picked at random: The SiLabs Si7210 [1] is a Hall effect magnetic sensors with 0.1% linearity and an I2C interface, no Arduino ADC to tame. The Si7210 tops out at 0.2T. Eval bords for the series ...

Most Arduino boards have an ADC chip with a 10-bit resolution that can output values from 0 to 1023. Popular boards like the Arduino Uno, Nano, Micro, and Mega are great examples of this.

Krejci’s design, while affordable, offers an 8×8 resolution, which is the maximum output of the AMG8833 infrared sensor array. DIY Arduino thermal camera Watch this video on YouTube .

Some of this light is directed down into the screen, towards an array of 64 IR sensors. By scanning through the sensors, you can determine the x and y position of the touch event(s) and use this ...

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.
