| ATtinySerialOut | Minimal bit-bang send serial 115200 or 38400 baud for 1 MHz or 230400 baud for 8/16 MHz ATtiny clock.Perfect for debugging purposes.Code size is only 76 bytes@38400 baud or 196 bytes@115200 baud (including first call) |
| AvrTracing | The last hope for the desperate AVR programmer. A small (344 bytes) Arduino library to have real program traces and to find the place where your program hangs. |
| BlueDisplay | This library enables an Android smartphone or tablet to act as a graphical display for your Arduino. |
| digitalWriteFast | Fast pin access for AVR microcontrollers |
| EasyButtonAtInt01 | Small and easy to use Arduino library for using push buttons at any PinChangeInterrupt pin. Automatic debouncing, no delay required. Functions for long and double press detection are included. |
| FrequencyDetector | Measure the main frequency of analog captured signal connected to an Arduino and check for noise and mute. |
| LCDBigNumbers | Arduino library to write big numbers on a 1602 or 2004 LCD. |
| NeoPatterns | Patterns for NeoPixel strips and matrixes including the patterns of the NeoPattern example by Adafruit. |
| PlayRtttl | Plays RTTTL / RTX melodies/ringtones from FLASH or RAM. |
| PWMMotorControl | Control brushed DC motors by PWM and uses optional attached encoders to drive fixed distances. For L298 or TB6612, or Adafruit Motor Shield |
| ServoEasing | Enables smooth servo movement. Linear as well as other (Cubic, Circular, Bounce, etc.) ease movements for servos are provided. The Arduino Servo library or PCA9685 servo expanders are supported. |
| Talkie | Speech library for Arduino. Generates speech from a fixed vocabulary encoded with LPC. |
