12/30/2023 0 Comments Arduino stepper motor step direction![]() Well, below is the code for completeing steps #1 & 2 (Stepper rotates CCW). Int step_period = 2 // Inter-step interval This code was based on the 1st assignment to figure out what is the max speed of the stepper motor before it stops moving: /*įull steps a stepper motor at 1 step/step_period Below is the code that my son needs to modify to the steps 1,2,3 above. Setup / Connections / Code that needs to be modified: We both been putzing around for a while now to no previal and came to the conclusion that we both need help or some advise. This causes the ULN2003 pin 2C to go to ground potential thus turning on coil 1b (see Fig. But there is a hint given: "The ULN2003 grounds whatever output is activated, for example, a 1 is output to Arduino pin 4 which is connected to ULN2003 pin 2B. He is not allowed to use any functions from the stepper motor library.
