Power Functions Recorder

Recording commands from LEGO Power Functions remote controls and playing them. Using IR Receiver Module Iduino ST1089 and IR 940 nm emitting diode.

LEGO Power Functions RC documentation: https://www.philohome.com/pf/LEGO_Power_Functions_RC.pdf

Features:

• all PF remote controls are supported
• saveing 10 recordings
• possibility to play in reverse order
• possibility to reverse commands from specified channel and output

Functions

• start/stop record - Button A or Rremote Control Red Forward
• start/stop play - Button B or RC Red Backward
• next record number - Button AB or RC Blue Forward
• previous record number - RC Blue Backward
• playing commands in reverse order - RC Red and Blue Forward
• playing reversed commands (from channel 1) in reverse order - RC Red and Blue Backward

** Sometimes program registers more commands because some commands are missed by LEGO PF receiver.**

⚠️ Warning!

Lighting the diode and the IR receiver with sunlight ☀️ or from an ordinary light bulb 💡 may interfere with the signal reception.
