You must complete lesson 1 (assembling the car) before you continue on with this lesson.In this lesson3, we will add a mg90 servo motor and to the robotic car built in Lesson 1.
Step1: Install Ultrasonic Module to mount holder with 4pcs M1.4*8 screw and M1.4 nuts
Step 2: Install mount holder for ultrasonic module on servo motor with M2*4 Self Tapping screw.
You must complete lesson 1 (assembling the car) circuit connection. No need to change anything, just keep the hardware wire connection as it is.
Step3:Please keep all lesson 1 connections same as it is.Before connecting wires, make sure that you have connect SG90 servo motor to model Y board and OSOYOO Uart Wi-Fi shield as follows.
Once you connects Lesson 1 wires, please connect two IR obstacle sensors as following:
Le
Step 1: Install latest Arduino IDE (If you have Arduino IDE version after 1.1.16, please skip this step). Download Arduino IDE from https://www.arduino.cc/en/Main/Software?setlang=en, then install the software.
Step 2: Download https://osoyoo.com/driver/mecanum_metal_chassis_m2/followme.zip, unzip the download zip file m2-lesson2.zip, you will see a folder called followme.）
Step 3: Connect Mega2560 board to PC with USB cable, Open Arduino IDE → click file → click Open → choose code “followme” in folder, load the code into Arduino as following.
Step 4: Choose corresponding board/port for your project, upload the sketch to the board.
