Node for measuring the amount of free Static Random Access Memory (SRAM). Based on https://github.com/mpflaga/Arduino-MemoryFree. For more information on getting the most from your Arduino memory, see: https://learn.adafruit.com/memories-of-an-arduino.

With this library, you can use several nodes at the same time, as well as rotate the servo not only with the help of a condition, but also with the help of a pulse signal!

The MAX44009 ambient light sensor features an I2C digital output that is ideal for a number of portable applications such as smartphones, notebooks, and industrial sensors. At less than 1µA operating current, it is the lowest power ambient light sensor in the industry and features an ultra-wide 22-bit dynamic range from 0.045 lux to 188,000 lux.

MQTT client to publish/subscribe messaging.

An attempt att making a node for a rotary encoder without any programming skills. Occasionally misses a click but works fine otherwise :)

The button is used to select an output for a menu or other function with a long press.

Button with short and long presses. Support for progressive impulses in long presses. Useful for setting up a value on a display.

XOD library for the SparkFun Pulse Oximeter and Heart Rate Monitor (SEN-15291). The sensor is an I²C based biometric sensor, utilising two chips from Maxim Integrated: the MAX32664 Bio Metric Sensor Hub and the MAX30101 Pulse Oximetry and Heart-Rate Module.
