In order to use a lot of animatronics in fursuit, it requires a lot of electronics to control them.
Electronics Control Units:
-
Stepper Motor (Wings)
To to able to extend wings, I have chosen to use Stepper Motors (4-wired) and Worm Gears. -
Voice
This unit is designed to pre-process fursuiter's voice to transmit using Central Unit and/or Walkie-Talkie Output. -
Servo and LED (Head Mimics)
Servo is controlled by Pulse-width Modulation. The pulse is from 1ms to 2ms (limits differ between manufactures) every 20ms.
RGB (multi-color) LEDs are 4-pin LEDs (one common anode, 3 cathodes (red + blue + green)). To use them, we will use PWM as for Servo but this time to simulate analog signal. -
Communication (Central) Unit
I was thinking - which type of communication to use. Best short-range communication is Bluetooth (because most handheld devices have it) but what to use for longer range? Bluetooth has range limit of about 20m. So I was thinking about 2.4GHz but I am still not sure.
In order to transmit data, I have created Communication Protocol. -
Power Preprocessor
For safety and to increase lifetime of electronics, I decided to place Power Preprocessor between Batteries and power usage.
Main part will be polarity protection (diodes) and I also want to include Voltmeter for all batteries and 5V output. -
Input Control
Because we have too many inputs from fursuit and fursuiter to be processed by Communication Unit, we need to use one Arduino Micro only for processing them (total 20 pins, 12 of them analog inputs).
