Welcome to the first lesson of Osoyoo Model-3 Robot Learning Kit!
In this “Hello World” version lesson, we will install the most important framework of the robot car and program the car to do some simple movements. If you have passed the test movement of this lesson, it means Arduino, motor control module, motors, batteries, chassis and wire connections between these parts are all functioning well.
As your experiments in future lessons are all based on the frame work of Lesson 1, it is very important to test the installation and sample code in this Lesson properly.
Connect UNO R3 board to PC with USB cable, open Arduino IDE, choose corresponding board/port for your project.
Notice: Shut off your battery or Unplug your power adapter when upload sketch code to Arduino.
Step 4:
Click file -> click Open -> choose code “lesson-1.ino”, load the code into Arduino, and then upload the sketch to the board.
Testing
Disconnect Arduino from PC, please confirm that the power switch of the OSOYOO Motor Shield V1.0 is off, put a 9V battery into battery box.
(make sure polar direction is correct, otherwise it can destroy your device and cause fire hazard).
Put the car on the ground, turn on the switch of OSOYOO Motor Shield V1.0, the car should go forward, then go backward, then left turn, then right turn, then stop.
If the car does not move as per above mentioned result, you should check your wire connection, 7 jumper caps on OSOYOO Motor Shield V1.0, battery voltage(must over 7.2v).
