More imformation, I am very new to arduino and the c++ programing language, I am trying to switch the direction of the motor every time I press a button however whenever I press the button the whole thing breaks and only 2 of the lights flash on the driver board. The reason I wrote out the steps is because the stepper library doesnt work for me. if you have any solutions that would be appreciated.

thx in advance

dam im an idiot thx

#define Button 0
. . .
pinMode(Button, INPUT); // Set the Button pin as input

• How is the switch wired ?

• Pin 0 on an UNO is the RX pin, what Arduino do you have ?

[orion_hallmark]

I dont think it is the wireing because previously I used someones code that reversed the direction after one rotation and it worked fine, all I added was a simple button circuit. I will work on a wiring diagram

[orion_hallmark]

I have an arduino uno, the button is connected to A0

[LarryD]

• Then use:
  #define Button 14

• How is the switch wired ?

[orion_hallmark]

[orion_hallmark]

the 5v and ground is connected to the pos and negitive on the breadboard, the button is connected to the 5v and A0

[LarryD]

@orion_hallmark

the button is connected to the 5v and A0

• Also add a 10k resistor from A0 to GND.

FYI

• Wire as S1 is wired, but the circuit is not generally recommended.

ok, my class in ending i will try your suggestions Thank you for helping a slightly stupid noobie

Thank you for helping a slightly stupid noobie

• Language like this is not needed.

It sounds like you may be better off putting the phone down and paying attention to the lesson.
