Source a nice and noisy germanium diode, give it a couple of op-amps to amplify and filter the noise before feeding it to that Arduino pin. Maybe you were thinking about radioactive decay and ...

When looking through existing Arduino drum kit projects, [joekutz] noticed that most of them just used the microcontroller as an input for an existing MIDI device. That’s fine if you’re just ...

To prevent the sensor from receiving too much noise during flight, the sensor was soldered to an Arduino ProtoShield ... as the transmitter and receiver. A motor connected to relay wires causes ...

Lucía Garbo has created an Arduino powered noise pollution monitor, powered by an Arduino Mega micro-controller and housed in a 3D printed case. Other components include a SparkFun Sound Detector ...

The landing gear being retracted or extended can cause significant noise, the retraction or extension of the flaps can have hydraulic motor noise, and the extension of the flight spoilers causes ...

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...

I want to point out that, especially if you are a headphone user, be aware that the Mach-E makes a horrible noise. Just the worst mechanical whine you can imagine. If anybody has a chance at ...
