GM37-3530 Motor and Hall speed

We choose a motor with higher accuracy, To make the balance car PID control more sensitive and more easier to stand,Use Hall sensor measures motor speed

description:

1. Voltage: 12v

2. Speed: 10-1000RPM

3. Reduction ratio: 1 / 10-1 / 1000.

4. Shaft size can be customized

5. Transmission length: 37 mm

6. Direction: CW CCW

7. Long life, low noise

GY-521Mpu6050 Module

The MPU-6050 is a serious little piece of motion processing tech. By combining a MEMS 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms, the MPU-6050 does away with the cross-axis alignment problems that can creep up on discrete parts. The breakout board for the MPU-6050 makes this tiny QFN package easy to work into your project. Every pin you need to get up and running is broken out to 0.1" headers, including the auxiliary master I²C bus which allows the MPU-6050 to access external magnetometers and other sensors.You can visit the following link ,https://playground.arduino.cc/Main/MPU-6050

Bluetooth module

HC-06 Bluetooth module can reach a maximum transmission rate of 2.1M/s, support Bluetooth SPP Bluetooth serial protocol,http://www.instructables.com/id/Add-bluetooth-to-your-Arduino-project-ArduinoHC-06/

Tb6612FNG drive module

TB6612 is a dual drive that can drive two motors,control story and reverse by controlling the truth table of AIN1, AIN2, BIN1 and BIN2.http://forum.arduino.cc/index.php?topic=19395.0

Last install of all modules

Note:pay attention to the connection of the power cord. Above the power terminal is connected to the red line VCC and the lower terminal is connected to the black line GND. If the connection is reversed, there will be a protection circuit inside the circuit that will not burn the circuit, but it will affect the performance of the entire circuit.

Balance car assembly

Motor mounting bracket mounting

Operating instructions:Use eight round head screws to pass through motor bracket and plate and secure with nuts.

Installation of motors, couplings and wheels

Main control board module installation

Battery box installation

Operating instructions:Use two round head screws to pass through the two mounting holes of the battery box and Acrylic, then use the nuts to fix the back.

Frame installation

Operating instructions:The second layer of acrylic board passes through the bottom 4 long copper pillars, and is fixed with 4 middle copper pillars. The top floor acrylic board is installed in the corresponding second layer of 4 middle copper pillars and fixed with 4 round head screws.
