WEEK 8.

For the solar oven I'm building with my collaborative design group we programmed a circuit that would detect temperature inside the oven and according to the temperature some LEDS would lit up indicating the degrees it reaches. We added a button as well so we can know when to start collecting the data of temperature. So for this circuit we needed a neon pixel LED strip, a button and a termistor.

We wanted to light up the leds one by one and light up in different colors depending on the temperature. So we would start from green then move to yellow orange and then red.

PROGRAMMING.

1.

We wanted to place the leds in a circular way for the termometer display so we had to cut the leds and solder them circularly.

2.

We placed the button in the middle of the display so that people could interact with it. We managed to connect it in the bread board and work with the leds and termistor. We also programmed it in arduino so the code could work for the 3 together.

3.

We needed to test first the individual circuits to see they worked well individually and then we tested them together.

4.

Once we got the code running we were able to assemble them together and test it.

5.

This is the schematic design we followed for the connections.

I did this as part of the fablab challenge so you can check our documentation in our repo here
