Objective:

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.

You must complete lesson 1 (assembling the car) before you continue on with this lesson.

Hardware Installation

Step 1: Install the smart car basic frame work as per Smart Car Lesson 1 . If you have already completed installation in Lesson 1 , please remove all wires on Osoyoo Uno R3 board

Step 2: Connect Bluetooth TX/RX ports to D4,D5 with jumper caps

Note: Our Wifi Shield Bluetooth TX/RX ports are connected to D4,D5 with jumper cap by default. If you find the Bluetooth TX/RX ports is not connected to D4,D5, you need use a jumper cap or female to female jumper wire to connect B-TX to D4 and B-RX to D5

Step 3: Insert to Osoyoo Wifi Shield onto your UNO board and connect OSOYOO MODEL X motor driver module and OSOYOO Wifi Shield as following graph:

Remember following tips restore your motor control system to lesson 1:

I suggest you run the sketch code in Lesson 1 and make sure motor connection is correct. This is very important for next steps.

Step 4: Insert Bluetooth Module into Osoyoo Wifi Shield Bluetooth slot as following graph:
