Given materials, I was tasked with designing and making a temperature sensing device which displays the temperature of a room and alerts users if the temperature falls outside of a specified range. I first started with modeling my components using Onshape and used these digital models to configure the layout of the components in real life. I then designed a holder for my battery in Onshape and 3d printed it. Next I tested circuit wiring in Tinkercad and used this to create a circuit on a breadboard. I then put all of the components together inside of the device enclosure and used soldering, wire nuts, crimps, and jumper pin connections to wire everything. Lastly, I created a code that the Arduino Uno inside of the device used to sense and display the temperature, and determine if it is outside of the desired range. When the temperature is inside of the desired range, a green LED is on to signal that the device is on, and the temperature is displayed on a screen on top of the device. When the temperature is outside of the desire range, an alarm sounds at a changeable volume and a red LED turns on.
