2. Main point of the project:
The reaction wheel pendulum is apendulum with a rotating wheel at the end,
which is free to spin about an axis parallel to the
axis of rotation of the pendulum.

6. How we did it:
1. Assembled the mechanical part2. Soldered the wires, connected
3. Finding a solution for working with an accelerometer and an engine
driver.
4. Debugging, nothing worked because of interference
5. They made separate power supply of the Arduino and motor,
remade the signal wires from the accelerometer, making them twisted
in pairs and transferred the driver directly to the motor
6. Selection of the speed of rotation of the motor and the algorithm
itself, so that everything swings and stabilizes
7. The result
8. And now…
9. Problems
1. Engine speed is poorly controlled2. Wires are too long and strong. Rather close to the signal, which
interferes with the accelerometer and drives him crazy with Arduino.
Even with separate power
3. Also, the wires press on the spinner itself, which interferes with
stabilization
