A library for Serial MP3 Player board (YX5300 chip). A library for driving LiquidCrystal displays (LCD) by using the I2C bus and an PCF8574 I2C adapter. Gives tone functionality with 10-bit volume control with no extra parts! Keypad is a library for using matrix style keypads with the Arduino. Adafruit_GFX-compatible library for IRM-Mini. Power save primitives features for SAMD and nRF52 32bit boards. (Works for all esp8266 boards also), Arduino library for DRV2667 Piezo Haptic Driver with Boost, Digital Front End, and Internal Waveform Memory, DRV8434S stepper motor driver library for Arduino. Arduino library for I2C DHT12 temperature and humidity sensor. Examples of spi cameras used on different hardware. Get rid of delay() calls, schedule tasks/functions instead. Ubidots library for the GPRS module SIM900, Library for sending data to the Ubidots cloud using ESP8266 based systems, Ubidots library for an XLR8 board with a WINC1500. Due to this, the design and documentation for the launch system in ROS 2 will need to be clearer when talking about processes and nodes. Library for the Sensirion SGP30 air quality sensor. Arduino library for interfacing with any GPS, GLONASS, Galileo or GNSS module and interpreting its NMEA messages. Vehicle Area Network (VAN) bus packet reader/writer.
