How to Integrate a Temperature Sensor Circuit to an LCD

In previous projects with temperature sensor circuits, we built the circuit and then got a readout on the computer that we programmed the circuit with. In this project, we take it a step further. Instead of getting a readout on the computer, we will connect the circuit so that we can get a readout on an LCD display. This mimics a more real-life-like electronic product which you would see on the market.
