1. Pin Array - 150 Pins (10 rows 15 columns) which can actuate vertically to provide tactile feedback to our users alongside the audio tours.
2. Pin Guide - Acrylic guide to make sure the pins are not wobbly when actuating.
3. PCB - 15 Printed Circuit Boards for 10 pins, 10 motors, 10 encoders, 5 drivers, 2 Arduino Nanos, capacitors and resistors each.
4. Motors and Encoders - 10 motors held by a motors holder on 1 PCB. One motor is responsible for the actuation of one pin.
5. Arduino Nano(s) - Micro-controllers to control the motors through the encoders. 2 Arduino Nanos on 1 PCB
6. Drivers - 5 drivers on 1 PCB. 1 driver controls 2 motors.
7. RaspberryPi - Micro computer that controls all the 20 Arduino Nanos
