PCOMP WEEK5
Lab 5
This week we are back with the labs using transistors to control higher current loads.
Connect Motor and Power Supply
This is my first time using the DC motor. After a week without the labs, I felt a bit disoriented when it came to how to connect the DC motor as well as the power jack.Since the 5V wall plugs ran out at the shop, I started the lab with the fancy power supply, which I was warned to treat carefully if I don’t want my circuit to be burned.
I connected the DC motor to the breadboard with alligator clips, and added a separate power supply with the switching power supply.
I had a very rocky start, as my motor was running but the code I put in Arduino was not doing anything to my circuit.
I checked my wiring over and over again, and started to check if each wired is inserted firmly. Finally when I pushed the diode down, the motor started working. I feel like this happend many times espcially when the wiring gets more complicated, making sure all the wires are connected correctly is a challenge in itself.
I played around with the potentiometer and adjusted the speed of the motor.
H-Bridge
By using the TB6612FNG motor drive, I was able to control the motor with a button. In the code, by making one motor driver pin high and the other low, I was able to change the direction of the motor immediately.
I would love to use the lamp example in this lab and use the light intensity as the output.
