Control Glove

Hi there. First of all I would like to thank all viewers because recently I hit 40.000 views on videos on my youtube channel and also 10.000 views on this blog. So few weeks ago I showed you beta of dummy, well I haven't been working on it so much since, I just made a PCB, but I've been working on this glove.

You might ask why glove ? Well because I always wanted to make one and I couldn't think of a better way of how to control Dummy. Even this glove is still in sort of beta state. It uses Atmega8 with the bootloader that has BOD (Brown-out detection) level set to 2.7V so this board can easily operate at 3.3 volts. I chose this option because of the fact that I wanted to implement battery to glove and that meant, that battery has to be small and light. I chose a battery BL-5B from an old Nokia. If you have one of these phones just laying around use that batteries, they have lot of power and 3.7 volts is all that you need. Board also have headers for FTDI or Bluetooth module, which operates at 3.3volts. Accelerometer that is for now the only sensor on this glove, operates also at 3.3volts which gave me the opportunity to use that Nokia battery and 3.3v regulator. Remember that when you are using different than 5V power source you have to put power on AREF pin and in the setup of the code declare that you are using EXTERNAL analog reference. In the future I would like to add few more sensors (probably flex). So I hope you like it and once again thanks for your support.
