Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

RS Components (RS), the trading brand of Electrocomponents plc (LSE:ECM), the world's leading high service distributor of electronics and maintenance products, has announced exclusive stock ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Based on the open-source Arduino Uno board,this new educational kit, currently available only from RS, aids entry-level electronics design The new starter kit has been developed together with a series ...
