 ===== Hardware Description =====
-I'll start with the ATMega2560. Pins D2(PE4), D3(PE5), D4(PG5), D5(PE3) are outputs for the 4-channel relay module. This system helps changing the direction of the track in one of the three directions, using 2 [[https://trennet.ro/produs/actionare-macaz-sine-piko-55271-ho/|switch machines]] that have 2 states. Those are powered by a 14V, 1.1A power supply.

-The pins that are used for the direction and speed of the train are D42(PL7), D43(PL6), D44(PL5). PL5 allows **PWM** so it is perfect for speed modulation. Those are connected to the **l298n motor driver**

 alongside a power supply of 12V, 0.5A DC.

-Here **Braccio**, a robotic arm made from 6 servomotors replaces the RFID tags. This is controlled through a **shield placed on Arduino Uno (ATMega328p)**. The communication between the 2 μC is facilitated by **I2C/TWI**. The pins used on the ATMega2560 are PD0 and PD1 and for the ATMega328p PC4 and PC5. Arduino Uno controls Braccio using 6 PWM signals for the 6 servos, PD3, PD5, PD6, PB1, PB2, PB3.
