Week 3- Lab day

Here we are, fresh and ready to start. The group decided to work on the code inputs for the newly made Stepper Motor circuit.
An example code was compiled into the mbed processor to check whether the different characteristics of the ARM processor will suit our proposed ideas for the new code or not, as well as to gain an insight on the different potentiometers on the processor. The example code was also used to check whether our circuit is ready or not. Proper marking of every wire was used for the purposes of labelling to avoid confusion while connecting the circuit.

Finally, we are completed with the circuit and the software part. Many efforts were put in it. Clamping diodes were placed accordingly on the circuit. Figure1 and Figure2 shows our complete circuit.

After that we connected the motor with it which is shown in Figure4. The ARM mbed processor was then connected with the rest of the components. Complete circuit can be seen in Figure4.

Now the task was to check it with a PC. The mbed has an online compiler which provides example codes to facilitate the coding process. We tested it and it worked with no problems.    
On the other hand, a group discussion was made about the poster design for the project. The plan for the upcoming two weeks was to spend time on the poster and finalising the project.
