Motor Driver Demos
For driving a DC motor via relays it was tricky reading which gates would actually be enabled when looking at the manual however it was straightforward after that.
The Transistor Relay was easy to set up however I was not able to operate it properly. My understanding of the Transistor was that it is a circuit with a semi conductor that only becomes conductive when that material is polarized. For whatever reason the conductor circuit would operate regardless of whether or not it was polarized. I rechecked the diagram as well as some online guides on the proper positioning of the transistor pins as well I manually tried reorganizing the pins if I somehow got the circuit wrong. I think my issue was either my power supply was causing issues or I misunderstood the use of the Transistor, I was able to get some pulses whenever the transistor was supposed to be set off so I think I misunderstood the use of the Transistor.
The TIP122 controller was pretty easy and straightforward, basically power 1 of 2 pins on the controller to power a circuit or reverse a circuit to reverse motor direction.
The stepper motor was tricky, at first I didn't understand how to pulse the coils to step it into a new position and just made the entire unit hot from the current. I tried using the A4988 driver to power what I realized might not be the proper type of stepper but was unable to operate it, I think if I come back to it I might be able to make it work regardless now that I was able to make it work with a ULN2003 driver which was just shifting which pins were one to snap the stepper position over. The A4988 is clearly more robust and designed for heavier motors so I will definitely revisit to properly set it up.
The servo was comfortably easy to operate with the Arduino library. It was basically like using Neo pixels but with even less setup just assigning data pins with a degree angle.
