Introduction: (WORK IN PROGRESS) Balance Board With Arduino Components to Track Your Balance and Improve With Technology.
For this project you'll need:
- Arduino I choose Arduino NANO because of the limited space I have in the balance board.
- 6 Axes accelerometer and gyro. (mine is the MPU-6050).
- Bluetooth or wireless connection (I've used bluetooth model HC-05). http://www.aliexpress.com/item/5sets-lot-HC05-JY-...
- Breadboard (not essential but it helps).
- Wires, connectors, resistors and welder when needed.
- One Balance board (like the one in the photo).
Step 1: Making Arduino NANO (Driver CH340) Visible to Arduino IDE:
(You can skip this step if it's your Arduino is visible in the tools>port.)
-For this step you need to download drivers, simply google "ch340 driver os x".
-Open and install the drivers and quit-reopen the Arduino IDE.
-Now in the tools menu you should get (one you choose the right board and processor) in the port menu a device with the name like this "cu.wch ch341 USB=>RS232 1410".
-Open the terminal and enter this command: "sudo ln -s /dev/cu.wch\ ch341\ USB\=\>RS232\ 1410 /dev/cu.USB42" this creates a link that is needed because the Arduino IDE does not support the spaces in the name of the port.
-Now you can choose the new name of the port in the tools>port menu and if you didn't change my terminal command should be "/dev/cu.USB42".
-Upload an example form the IDE File>Example so see if the Arduino is fully working.
Step 2: Connecting Arduino and MPU-6050
Quite easy step:
MPU6050 - Arduino pin
INT - Digital pin 2
VCC - 5V
GND - GND
SLC - A5
SDA - A4
Step 3: Connecting Arduino and HC-05
Easy step #2:
HC-05 - Arduino pin
VCC - 5V
GND - GND
TX - Digital pin 4
RX - Digital pin 5 (look at the image to change voltage from 5v to 3.3v)
We have a be nice policy.
Please be positive and constructive.
