Arduino Mega2560 User Manual

Lesson 4: Bluetooth Imitation Robot Car
In this lesson, we will use Mobile to control our robot car and make an imitation
driving. Since is a mock driving, we will use a virtual steering wheel and gear in our
APP to imitate their counterparts in real car.
In this lesson,Mecanum Omni wheel will allows robot car make omni-directional
movement( parallel shift to left and right).

You must complete lesson 1 (assembling the car) before you continue on with this
lesson.No need change anything, just keep the hardware wire connection as it is.
STEP1: Connect B_TX and B_RX to D19 and D18.
(Note: You need split 2 pcs of male-to-female jumper wires from our 10-pc jumper wire
bundle. Any color from the bundle will be ok. The rest of 8 pcs wires are as spare parts
for potential broken or damaged wires.)
