His most recent exploit is to use the I2C-controllable chip to implement a Fast Simple QSO (FSQ) beacon with an Arduino. FSQ is a relatively new digital mode that uses a form of low rate FSK to ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

[Jordan] managed to cobble together his own version of a low resolution digital camera using just ... is connected to an analog input pin on an Arduino. The sensor can be pointed at an object ...

Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations. Digital control of switch-mode ...

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes ...

If you like decorating your house for the holidays, these digital LEDs save the trouble of manual teardowns by using Arduino to modify animation effects each season. Instructables user CarlS ...
