Assembly of the Pi Plate for the line
following robot
The Pi Plate is necessary only if you are going to build your own circuitry
(instead of an off-the-shelf robot kit) that drives the robot.
We will make use of the Pi Plate from Adafruit Industries. The Pi Plate is stackable and
an add-on hardware for the Raspberry Pi. The Pi Plate is like a breadboard/perforated
prototyping board and enables prototyping using the Raspberry Pi plaform. We will
assemble the headers on the board.
Prepare for lift off
USD. This stackable add-on hardware is useful because the sensors and actuators can
be connected using the screw-in terminals. This will avoid any loose connecions to your
Raspberry Pi while the robot is in moion.
