There could be many reasons why your Arduino code is not working properly with your stepper motor. Here are a few things you can check:
- Make sure you have the correct pins connected: Stepper motors usually have four wires that need to be connected to the Arduino. Make sure you have the wires connected to the correct pins on the Arduino.
- Check the wiring: Make sure that the wiring is correct and that there are no loose connections.
- Verify that you are using the correct library: There are many stepper motor libraries available for Arduino, so make sure you are using the correct one for your specific motor.
- Check the power supply: Stepper motors require a higher voltage than the Arduino can provide, so you may need to use an external power supply. Make sure that the power supply is supplying enough voltage and current to the motor.
- Check the code: Make sure that the code you are using is correct and that there are no errors. Double-check that you are using the correct library functions and that the parameters are set correctly.
- Check for mechanical issues: Make sure that the motor is properly mounted and that there are no mechanical issues, such as binding or resistance in the motor or gears.
By checking these things, you should be able to identify and fix any issues with your Arduino code and stepper motor.
If the switch is on, and the sketch counts to 90, the sketch will see the switch on again, and continue from 90 to 180.
Where do you store the "last switch position" for a power cycle?
