Sjoerd’s Glove

Sjoerd van der Sanden has built himself his own ArduIMU Glove! Instead of using Glover to receive the ArduIMU stream of sensor data the data is now sent as ASCII and directly read into Max/MSP via the serial port.

Arduino Sketch

The ArduIMU glove firmware code was modified to enable ASCII packets (comment out line “#define BINARY_PACKETS”). Source code available here:

https://github.com/SebMadgwick/ArduIMU-Gloves

ASCII packet protocol:
F,1,2,3,4,5,6\r = flex sensor data for 6 sensors
S,gx,gy,gz,ax,ay,az,mx,my,mz\r = IMU sensor data (gyroscope, accelerometer, magnetometer)
Q,w,x,y,z\r = quaternion

Coding session to get ArduIMU receive working

Getting the ArduIMU to receive values to control LED light and vibration motor.
Arduino code >> https://github.com/plusea/CODE/tree/master/PROJECT%20CODE/Gloves/ArduIMU%20Gloves/Sjoerds%20Gloves

Our solution for interpreting received bytes and mapping them to control the RGB LED and vibration motor strength is very inelegant, but simple. In the Receive.cpp tab of the Arduino code you’ll see following lines of code. To keep it simple we restricted the receive interpreter to only having to work with a single byte, so values from 0-255.

Read incoming serial value:
int incomingValues = Serial.read();

If the incoming value is between 0-50 then scale this value to full range of 0-255 and control vibration motor:
if(incomingValues >=0 && incomingValues <= 50) analogWrite(10, incomingValues*5);

If the incoming value is between 50-100 then scale it and control red of LED:
if(incomingValues >=51 && incomingValues <= 100) red=incomingValues-50;

If the incoming value is between 100-150 then scale it and control green of LED:
if(incomingValues >=101 && incomingValues <= 150) grn=incomingValues-100;

If the incoming value is between 150-200 then scale it and control blue of LED:
if(incomingValues >=151 && incomingValues <= 200) blu=incomingValues-150;

Set LED colour:
LEDs::setled(red*5,grn*5,blu*5);

    Hi, how would i go about sending data to the gloves from Max to mess with the LED colour etc? And what data will it accept? I can’t quite make it out in the video. Great patch and code by the way, great work =]

    good question! have added answer to post above. let us know if anything is still unclear.

    :-)

    Thanks, works great for me!
    For anyone wondering, just create three sliders each with a range of 50, producing values of 51-100, 101-150 and 151-200, pack them using a ‘pak’ object (not @pack@, that’s important in my experience) and send that to the top input of the ‘serial’ object at the top of the patch.

    Example patch:

    Thanks for your post. With the Motor included, it would look like this:
