Research Stage 2,
26/11/18 - 3/11/18:


Parts:

For my first prototype (P1), I chose to use the most simple equipment I could find to mock-up the power system for my motor. For this test, I just wanted to produce a mock-up that would allow me to adjust the speed of the motor with a throttle of some kind, using batteries which are similar in voltage to those I plan to use in my final version.

Parts used:

Motor:

Batteries:

Arduino Uno:

I also used some jumper wires and a 50k Ohm linear, sliding potentiometer, as listed in the tutorial I used [here](http://rztronics.com/control-brushless-motor-using-arduino/)

All set up:


**Test Video:**

Open E-Bike - Pot. Throttle Test from Conor Croasdell on Vimeo.

Results:

The motor increases and decreases RPM as the potentiometer is adjusted. Now that I know the control works, I can build a way of mounting the setup onto a bike for a first working mock-up.
