How to connect Wii Balance Board to Arduino board?
We have a Wii balance board pressure sensor and were wondering how we could connect this sensor to an Arduino board. On the circuit board (see picture) of the Wii Balance Board are Japanese characters printed, only those are pointing out which color there must be.
How many sensors does a Wii Balance Board have?
It has two TI ADS1222 2 channel Serial ADC converters, for four sensors total. The two smaller ics labeled TI 93 DBA3/DBAQ are probably opamps (can’t find the part) but they should trace out to the ADC converters. Most likely, LMV932s, dual low voltage high quality opamps, but they don’t match the suggested topcodes.
How many cables does a Wii pressure sensor need?
The problem is, most pressure sensor examples of the Arduino are with 2 cables, but the Wii pressure sensor got 4 cables. So which cable is for what? It has two TI ADS1222 2 channel Serial ADC converters, for four sensors total.
Are there pressure sensors that work with Arduino?
Glowing LED to detect the increase in pressure by pressure pad using Arduino. An Arduino-based altimeter, mostly for model rocketry. CPS120 is a high quality and low cost capacitive absolute pressure sensor with fully compensated output.
How does bleeding work on an Arduino Balance Board?
Bleeding is done by dissipating some power through a resistor/switch combination controlled by a microcontroller. This instructable describes a passive balancing system compatible with the arduino/LTC6804 BMS from a previous project. You can order the Balance Board PCB from PCBWays here:
What is the library for Arduino self balancing robot?
The LMotorController library is used for driving the two motors with the L298N module. The I2Cdev library and MPU6050_6_Axis_MotionApps20 library are for reading data from the MPU6050. You can download the code including the libraries in this repository .
How does the BMS work on an Arduino?
As the pack is charged, the lower capacity cells will reach their maximum safe voltage before the rest of the pack. The BMS will detect this high voltage and cut off further charging. The result will be that much of the pack is not fully charged when the BMS cuts off charging due to the higher voltage of the weakest cell.
