This project is an Open Source gate controller for BMX gates. You will need to build the controller yourself.
Please see:
- spoken cadence
- random start
- remote control
- light tree
- Conforms to BMX Australia / UCI gate cadence
- Arduino based micro controller with 11 digital IO pins
- This design has been proven to run on the Arduino Uno (both the Adafruit Metro, and Robotdyne Uno clones)
- It also runs on the ESP8266, but you will need to change some of the pin references
- Soundboard, I recommend the JQ6500 model. The Adafruit SoundFX boards also work
- Amplifier module
- Trim pot (TBA: trimpot value)
- Diode (TBA: diode value)
- Resistors (TBA: add suggested values)
- Big fancy start button
- Enclosure of some sort
- Electro magnetic latch (I used a 280kg Ebay sourced magnet)
- 12v supply (can be power brick, or car/motorbike battery)
- (optional for light tree) NeoPixel stick (Adafruit or Banggood clone)
- (optional for remote control) remote module
- any remote module will work, as long as it can trigger a signal on one of the input pins
- (optional) barrel jack and switch. You can omit these if you want to use the barrel jack on the Arduino, and let the unit switch on when plugged in
- The MOSFET circuit (with diode, LED, and MOSFET) can be switched out for a MOSFET module, or relay module.
- The resistor values for the LEDs vary depending on your LED model and how bright you want it. Use a breadboard circuit to determine these.
| Pin | Jumper | Notes |
|---|---|---|
| pin 3 | None | Default Light tree is a neopixel stick, controlled via serial protocol |
| pin 3 | Ground | Sets "light tree relay mode". Triggers relays on PINS A0,A1,A2,!3 for light tree. |
This project can be built using the Arduino IDE, or on the command line:
user@host$ make
