#This is an Arduino 2.4GHz radio and IR transmitter

Features:

  • IR transmitter for "LEGO" Powerfunctions and trains as well as for "MECCANO" motors
  • 2.4GHz radio transmitter for RC cars, helicopters etc.
  • 4 analog axes, 2 mode switches (joystick buttons)
  • 4 push buttons for transmission mode and vehicle selection as well as menu navigation
  • 5 seletcable vehicle addresses, so you can use it for more than one vehicle
  • 3.3V, 8MHz Pro Mini (a Pro Micro is not supported anymore due to additional functionality)
  • 2.4GHz NRF24L01 radio module
  • Support for 0.96" I2C OLED
  • Configuration menu for: Channel direction reversing, servo travel adjustment (independent for each vehicle)
  • Configuration values are stored in EEPROM
  • NRF24L01+PA+LNA SMA radio modules with power amplifier are supported from board version 1.1
  • very compact
  • Eagle PCB included

New in V 1.3:

New in V 1.4:

  • 10 vehicle addresses instead of 5
  • The "BACK" button can now be used (if the menu screen is not displayed on the OLED) as a momentary button, for example for a horn on the vehicle. It is sent as "data.momentary1"
  • The "A6" potentiometer connector is now integrated in the code and is sent to the vehicle as "data.pot1"
  • SimpleTimer library replaced with my own code, which uses significantly less memory
  • EEPROM reset function added: press "Select" and "Back" during power on

New in V 1.41:

  • Transmitter battery voltage now monitored correctly on 16MHz / 5V systems

New in V 1.42:

  • Vehicle battery state change OLED bug fixed

New in V 1.43:

  • Radio module sleep mode active while IR mode is in use

New in V 1.5:

  • MECCANO IR support enhanced. Requires MECCANO library update to V 1.1

New in V 1.6:

  • Buttons locked, if not required in selected transmission mode. This ensures, that no variables can be changed "in background"
  • Automatic joystick zero point calibration after transmitter was switched on. This ensures, that you always have precise zero points, even if your potentiometers are not exacltly linear.

New in V 1.7:

  • Support for 2 channel car style transmitters with steering wheel
  • The transmitter type can be seletced in the new "transmitterConfig.h" file
  • The potentiometers in some transmitters hit the mechanical endstop before the end of the electrical range is reached. This can now be compensated with the "range" variable

New in V 1.8:

  • In most car style transmitters, the reverse range of the throttle potentiometer is smaller than the forward range.
  • The reverse range is now multiplied by 4, to solve this problem
