Project Development.

Assignment

Complete your final project, tracking your progress:

Q. What tasks have been completed, and what tasks remain?
Q. What's working? what's not?
Q. What questions need to be resolved?
Q. What will happen when?
Q. What have you learned?

What is working .

My heating pad was working and while trying with 9v it was not giving enough heat I even tried using 18v volt. While working with the DHT22 sensor it was working well and even the serial monitor was working well with right temperature reading.

Moment of truth

I was done with physical fabrication. After lots of procrastination for physical fabrication I was finally done with physical fabrication. This was the first time for me to do stitching using sewing machine. planning how to sew before doing on the fabric, after practising for few minutes it was very interesting

What is not working .

The DS18B20 sensor was destroyed as it was connect to my board although it was my 3rd board and i was not able to work with the sensor. When i tried with arduino it was working and when i try with the board it was giving problem. So I changed my sensor and used DHT22 sensor. The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Task remained

I have to work on my board and work with the heat pads since the heat pads requires 18 volt and my board can handle only 5 volt and for that reason i am using voltage regulator on my board and I tested with the 18 volt giving from the power supply.

I also have to make the mosfet to turn on and off for the heating pads.

What is working

My board is working with the sensor.

physical fabrication is almost done with the decorations on.

What is not working

The sensor DS18B20 Sensor was not working so i had to change the sensor. Heat pads were not working with the board since the mosfet was given in wrong connection so i have to change it.

What Question needs to be resolved.

I need to mill a new board again after debugging

Need to test the heat pads after changing the mosfet.

What will happen when?

For completion of my project I need make a schedule.

What have you learnt?

After doing all the weekly assignment. I have leaned how to sew first of all,

I even learned how to use the heavy machine like zund

I even learned how to use the machines like CNC,3D printer,Leaser cutter and designing board on eagle,

I even learned how to read the data sheet (Voltage regulator and mosfet.)
