Parts

This project was based off the work in the RC with Adaptive Controls for Disability: How To Guide YouTube video.

Arduino Parts for RC Ghost Trap

This worked, but I really wish I'd gone straight for a Teensy 4.1 :)

Arduino Uno ($22.54 each) Amazon Link
Adafruit i2c LCD ($19.95 each) Adafruit Link
USB Host Shield ($4.99) HobbyKing Link - lots of clones of this board out there, this is just one example.
- Note that these shields are LOW-QUALITY and may be missing the voltage jumpers (solder blobs), etc.
3D printed case Thingiverse Link

iRangeX IRX4+ transmitter ($55.99 each) Banggood Link
- To bind the IRX4+ to the AR410
  - New firmware download: From the [multi-module firmware page] choose the IRX4+, then the ppm-aetr firmware.
  - New firmware flash: flash-multi tool - note that on the new module, I was getting errors and I had to use the advanced menu to write the bootloader first.
  - Set Bank to 2 - Instructions and you can see the required setting in this file multi-module firmware config.h
  - Set Protocol to 1 (1 through 8 are all DSM modes, I tried 1, it worked, and I stopped testing)
  - Press the binding button on the AR410 receiver, and boot the Arduino system with the IRX4+ (Make sure the Arduino is already setup, sending signal and wires are connected between the Arduino and the IRX4+ transmitter.
- We had a lot of trouble with the connector on this device, so I opened it up and soldered pins into it. Problem solved.
SPEKTRUM AR410 receiver ($34.99 each) Amazon Link
RC Switches
- Elechawk 4A RC Switch ($9.50 each) Amazon Link
- APEX 3A RC Switch ($11.99 each) Amazon Link
- DO NOT BUY THIS POS - Dilwe RC Switch ($11.98 for 3) Amazon Link - this switch requires you to sweep low->high->low->high to cycle on, then low->high->low->high to cycle off.
Extended length .1 inch pin header for the connection to the RC transmitter and on the Uno for extra solder points

XBOX ONE USB Controller ($24.69 each) Amazon Link
Voltage Regulator - 800ma ($8.89 for 10) Amazon Link - using one of these to step the RC car voltage down to 3v for the original toy ghost trap lights & sounds which will be switched by an RC switch
Voltage Regulator - 3a ($11.99 each) Amazon Link - using one of these to step the RC car voltage down to 5v for the flashlight "headlights" for the RC car
3v relay (bought a relay cheap board from amazon, then pulled off the relay component for size) - this was needed because the soundfx board needed constant power and then to have the trigger activated using the 3v relay.

Adafruit Sound FX board ($29.99 each) Adafruit Link
- In the end, the onboard amp was not enough power, so we went to the powered bluetooth speaker setup and soldered on a male headphone cable
Adafruit 1/8" headphone cable (we soldered on to the Sound FX board)
Insignia Rugged Bluetooth speaker ($20) Best Buy Link
Multiple types of push button switches for sound board trigger
