Calorimetry Part 2: Temperature Probe & Integrated Circuit

Today, me, Zach, and Sam continued our work in the calorimetry project. We were supposed to just do the temperature probe, but we ended up also building the motor circuit and creating code that used them both plus the mechanical relay. We rewired the mechanical relay to be more compact so we could fit the other two circuits on the board. I’ll get a video of them all working together soon. The goal is to mix a solution while monitoring the temperature, and based on the temperate the motor will change its speed. The LED is there to tell us what the Arduino is doing. Our 3D printed stirrer was printed today as well, here it is:
