This library enables you to use Hardware-based PWM channels on AVR-based boards, such as Nano, UNO, Mega, Leonardo, 32u4, etc., to create and output PWM. Using the same functions as other FastPWM libraries to enable you to port PWM code easily between platforms.

This library enables you to use ISR-based PWM channels on AVR-based boards, such as Mega-2560, UNO,Nano, Leonardo, etc., to create and output PWM any GPIO pin. It now supports 16 ISR-based PWM channels, while consuming only 1 Hardware Timer. PWM channel interval can be very long (ulong microsecs / millisecs). The most important feature is they're ISR-based PWM channels, supporting lower PWM frequencies with suitable accuracy. Their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These ISR-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using millis() or micros(). That's necessary if you need to control devices requiring high precision

Récepteur HUBSAN

Flappy Bird-like game written for the Arduino Uno.

Believe it or not, this is just a simple 3-LED traffic light , but it’s written in bare-metal AVR instead of using delay() and digitalWrite(). That makes it ~60–120× faster and far more efficient than the normal Arduino way — the CPU stays free while the hardware timer handles the timing baby.
