Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – 3 ; 1K ¼ w Resistor – 3; Schematic of Arduino PWM LED Controller Circuit. Advertisement. Arduino Sketch.

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 ...

However, the only Arduino platform included is an Uno R3. You can still create different circuits with this board, though, especially if you're primarily working on beginner projects.
