Note: This readme is a work in progress - the project is still under development
Sketch for a self balancing arduino robot using an Arduino Uno, a MPU6050, NEMA 17 motors and two A4988 drivers.
- GND/VCC shared with the rest of the circuit - perhaps change GND to second arduino gnd.
- SDA/SCL to A4/A5 respectivly
NEMA 17 motors with 4 wires scheme:
Both motors are wired to their own A4988
- VMOT/GND external power supply - GND can be shared with the rest of the circuit;
- 2B - Black Wire;
- 2A - Green Wire;
- 1A - Blue Wire;
- 1B - Red Wire;
- GND/VDD shared with the rest of the circuit logic power supply;
- MS1 to MS3 all to HIGH to allow microstepping;
- STEP and DIR - the input PINs assigned to the step and dir functions.
Current wiring of the A4988 and Arduino - motor wires not connected for image readability sake.
- Orange and Yellow wires are step and dir (respectively)
- All the MS are connected to Arduino 5v
