My XT90 connectors arrived, so I installed them on my charged batteries and Electronic Speed Controller. I am impressed by their heat resistance because I had to hold the soldering iron on them for a long time. Now I understand why there is a market for heatsinks designed for these connectors. I made three shielded banana plug extensions to link my ESC and motor.
Upgraded parts
I modified my Arduino program to use standard servo/ESC timing instead of my hobby servo's expanded time range. I kept the servo attached as visual feedback, but it only moves 90°.
I won't use the pushbuttons to control my speed if I'm wearing the skates because the likelihood that they would go out of control before I could press the correct button is too high. I installed a spring-to-center joystick and mapped the input to a percentage. I created a function that turned the 0-100 into a timing pulse, which is what the Arduino servo library does, but I have control over my code. The code also recognizes when I push down on the joystick and will report it as "braking," but it doesn't take any action. I tested the apparatus, which lacked strength at low speed but could apply power and accelerate once I got to a jogging pace. I could have gone faster than my test, but it got scary.
Speed and servo angle are proportional, cat toesies are optional
