Copy of std Ultrasonic range, but returns Max distance on failure so we can assume nothing close to us. My sensor seems to go low on ping capture, not success, so I changed timeout to max round trip to get full range.

Hysteresis node to filter the input signal

Index nth string selector (1-4 strings)

Contains encoder KY040 patch, digital pullup input patch, example of usage. Encoder reads boolean inputs to obtain numerical value of revolution. Boolean outputs are used for clockwise and counterclockwise direction detection respectively.

Read IR remote

General Utilities. Updated for XOD v0.28.x (makes queue-buffer pins generic); add 'all' node

Random numbers generation

A crash course tutorial baked as a project

Additional nodes for comparing numbers

MCP4725 12-bit I²C DAC Driver library

8 Segment display node

Expanded h-bridge node to handle h-bridge with 2 direction pins for a single motor. - Updated for XOD 0.31.x

The next step in your learning once you understand the simple traffic light example provided in the XOD documentation. Updated for XOD 0.32.1; added mutex, bus, and jumper examples.

Enhanced servo implementations to detach servo and allow it to free-wheel (or allow other nodes to control the servo)

Update LCD display on I2C. Specify Columns and Rows. Init pin can be used to prevent extra clear displays. Passing null string for a Line will leave the line untouched; space will clear a line. Variadic pins for rows of text to display.
