This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital approximation of a sine wave, which is then ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is used ...

Intersil has introduced a PWM (pulse width modulation) controller with a programmable switching frequency and programmable soft start. The ISL6420A also integrates control, output adjustment, ...

National Semiconductor has introduced the LM5033, a 100V DC-DC PWM (pulse width modulation) controller aimed at intermediate bus architecture (IBA) designs. IBA controls the multiple low-voltage power ...
