Week 13-14

What was your group trying to accomplish this week?

• Take apart the mister and plug it into the Arduino.

• We tried to get a smartphone to communicate with the Arduino using a Bluetooth module.

• Using an app made on Arduino to operate the modules on a smartphone

• Getting the karting game exported from unity and imported into android studio so that we can download it onto an android phone

What got done? (Include photos/videos/screenshots as evidence.)

• We took apart the mister and took out the circuit. We thought it would work with DC circuit and could just plug in the atomizer mister part into our Arduino and program it like the fan. We found out that the mister works with AC and we would need the circuit it came with.

• We had to solder the wired back together but the mister works by sliding a side down. So the mister was also controlled by a magnet with a hall effect sensor. We decided we didn't want to have to work with moving a magnet inside the module so we ordered an atomizer mister with a simpler on an off system.

What didn’t get done? What did you do to fix it?

• We had to order a new Bluetooth module (we are trying an hc-05 rather than an hc-06) which unfortunately does delay us a couple class periods as we wait for the amazon order to arrive, so our work with the Bluetooth module did not get done.

• We continually tried to pair the Bluetooth module to both Deniz's android phone and a computer (which the emulator is on), and it would pair, but it wouldn't remained "connected" in order for us to actually test the application out. The module we have has only four pins, which might be the issue, but we're not too sure.

What did you learn?

• To do more preliminary research about the parts and circuits we're buying so that we don't have to rebuy a part that doesn't work properly or so that we don't ruin working parts.

• We learned how to solder

• We learned to not disassemble circuits that we might need later on

How did the design thinking process show up in your work this week?

This week was mainly taken up by prototyping, we've been creating the first prototypes for the mister and smell module. We will continue to follow the design thinking process when we finish, and move on to testing.

What are your plans for next steps moving forward?

Once our orders come, we should be able to move forward. The Bluetooth module will ideally allow us to test our code and develop the application. The new mister should allow us to make more progress on that module. We also need to solder around the button on the new mister. We will need to be able to use the power to turn the mister on and off. The button would need to be pressed after the power is turned on but by soldering around the button or taping the button down. the mister would be turned on and off with the power.

Using DC power to power the mister. We need to find a female plug to plug into the circuit and then we will use the male sides to plug into the Arduino. We will then use the Bluetooth module + app to control the power to the circuit.
