For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned pin to output a PWM signal whose on time is in proportion to the written value.

Although it’s technically possible to get 16 bits of resolution on a ATMega328, most implementations of PWM on everyone’s favorite ‘mega – including just about every Arduino… ...

The Arduino library authors elected to detect that edge case and just force the output pin to go low in that case. When inverted, however, the pin still goes low when it ought to go high. You can ...

Schematic of Arduino PWM LED Controller Circuit. Advertisement. Arduino Sketch. Advertisement. ... Here, the three LEDs are directly connected to Arduino pins with independent current limiting ...

While both Atmel and Microchip make excellent prototyping systems, the popularity of Arduino/Genuino in maker communities means there is a lot of cheap easily-accessible AVR hardware out there, some ...

It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...
