Coding Dojo with Lego train

This coding dojo is inspired by Youtube channel Arduino Lego Trains and the site Internet of lego.

Raspberry Pi 3 Model B

Black = Ground (GND), Red = 5V (VCC), Yellow / Blue = Signal (GPIO / DI / DO)

GPIO = GPIO on Raspberry Pi

1. 5V and ground connect to IR-remote (5)
2. Power and signal cable for motor. 3-pole contactor to motor controller (4). Yellow to GPIO 25, Blue to GPIO 23 and 24
3. Cabel to Lego motor. Connected to motor controller (4)
4. Motor controller (Dual H Bridge Stepper Motor Drive Controller Board Module For Arduino L298N CF). Control for the gear motor. Supplies motor and IR-remote with 5V
5. IR-remote (Infrared-led 5mm, 1.35v, 100ma, 925mm). Resistors for regulating the current. You can buy premade on eBay
6. Photo resistor sensor module detector board
7. Signal connects to GPIO22 and DI on IR-remote

Operating system used on the PI.

LIRC is need to controll the train with IR. Follow the instructions from Internet of Lego http://www.internetoflego.com/lego-train-automation-ir-power-functions-with-nodejs-and-lirc/

LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls.

LEGO Power Functions LIRC (Linux Infrared Remote Control) https://github.com/dspinellis/lego-lirc

The IR-remote is controlled with LIRC.
