Reflection

1. If you have the idea, its just a matter of how the idea is approached with steps and necessary learning in between that makes it work overall.
2. It was quiet an experience. I was terrified in the beginning of the whole idea. But then, after reading the basics, I just started by trying the RGB Led. The program were available online and so was the board diagram. This made it easy. Then it was a matter of understanding the program and tweaking it to achieve what I wanted.
3. The Original Idea was to sense the temperature of the inside part of meat in Oven. But the available sensors and devices would not be able to handle oven temperature. Hence, the idea was downsized to measuring a hot food/liquid. 

4. By doing so, I was able to learn the know hows of executing this idea and have a IOT Device which could be a real life solution with right ingredient of components.

5. The next step would be to incorporate an input medium where a temperature can be preset and then the device would start working and notify the user when its done. Or even better, maybe the IOT Device would turn off the oven after reaching the preset temperature.
6. Making music out of the piezo would be a nice experience next time.
7. Should figure out to control the notifications as once the temperature is achieved, it kept on notifying until the device was turned off or temperature came down. This could be like spamming the message box which is not desirable.
