Redmond, Wash.&#151 RPM Systems Corp. has launched its MPQ-AVR, a four-port, in-circuit programmer for Atmel AVR microcontrollers. The system features on-board flash storage of program images, and ...

Sometimes it’s nice when you can do everything you need to do with just one single port. In this vein, [Nicola Strappazzon] ...

It’s not that breadboarding AVR circuits is difficult. But you have to admit that it takes some time to set everything up. We don’t label the top of our DIP chips so that you know what each pin does ...

Voltage regulator IC’s, with 3 pins, from LM7805 and LM7812 series are excellent for usage in voltage regulator circuits. If you need higher currents, up to 3 A, you must add a complementary ...

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication. Fig 1. This voltage regulator circuit (a) uses green ...

QUESTION: There are so many different voltage regulators on the market these days. How do I pick one that will be good for my circuit? ANSWER: Wow, this is a tough question, but also a good one. I’ll ...
