Today I further explored the Arduino Levitation that we had hoped to use as part of our final proof of concept model. I explored this possibility back in week 8 (click here for posts:
Week 8 - Testing the Concept (Group Workshop) &
Week 8 - Arduino Levitation Research) and had put together a list of the components required. This week we collected all the components and I assembled the circuit to test the input and output. The following photos document my findings:
 |
| Components laid out and ready to go. |
 |
| Resistors checked for correct values and labelled. |
 |
| This diagram maps out the basic set up at the point of levitation. |
 |
| This is the circuit diagram for the coil driver. |
 |
| This is the circuit diagram for the sensor data collection. It includes a signal amp to amplify the signal coming from the Hall Sensor. |
 |
| Circuit assembled with the sensor data collection circuit taking up most of the breadboard and the coil driving circuit taking up the last four rows of the breadboard. |
With this assembled we were able to test the signal provided by the Hall Sensor through the amplification circuit. I was happy to find that the circuit was infact assembled correctly however we found it wuite strange that the signal provided was actually much more stable and consistant when the amplification circuit was disconnected leaving the Hall Sensor with only the capacitor to smooth out the signal.
Even though this had been a success I found out earlier today that the program that was online up until a few days ago had been removed. To create the program would take significantly more time and having read the tutorial for the circuit more carefully I found that alterations to the Arduino's internal coding also had to be made... this is well beyond my abilities so it was time to call it quites on the Arduino Levitation for now. :(
For the purpose of the proof of concept model we are able to fake it because we know that magnetic levitation is possible.
