As I always built a board for the Input Devices assignment, I choose to spend time with programming.
My skills about programming are so pathetic, it will be an opportunity to develop this point.
I have to control a step motor, it's a major part of my final project.
I used a large Nema 23HS30 stepper motor and a driver M542T.
Here's a schematic showing how the driver and motor work:
To begin I just adapted a basic blink sketch, the motor is running.
After that, I tried to make an alternative movement, I also used the "pulse" fonction.
A 3.3v regulator
As I'll have to use a Bluetooth shield for my final project, I decided to make a new board.
The HC06 I own, needs 3.3V, so I have to design a specific regulator, as usual I'll use Eagle.
I added a tension divider to send serial correctly to the Bluetooth shield.
