Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement.

What Are PWM Pins? The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15.
