Original Circuit Diagram: Arduino UNO R3. Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

ATmega168 microcontroller; 78L05 voltage regulator; 100uf electrolytic capacitor; ... the microcontroller, or both. The circuit schematic. Above is the circuit we are using as an example.

We love looking at hardcore electronics projects with a beefy microcontroller and hundreds, if not thousands, of lines of code at its center. But everyone needs to get there somehow. This tutorial … ...

What you need is a microcontroller. This article provides step-by-step instructions for setting up a complete development system for the Atmel AVR series of microcontrollers, using free software and ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...
