Week 10 - Labs, Labs, Labs

First lab: using a Transistor to Control High Current Loads with an Arduino

Setting the bread board:

After I connected everything I wrote the code in the Arduino program, this is the result:




Lab: Controlling a Stepper Motor With an H-Bridge


First I connected the board:


Because the stepper motor has so many wires this illustration of the H-bridge really helped me to understand where I'm connecting every wire:

Then wrote the code an got this call:

It counted steps!

Then I change the code that it will count the number of steps per revolution:

This was the call


And this was the motor movement
