In this project, we will go over how we can build a temperature sensor circuit and integrate it to an LCD so that we can get a readout of the temperature on the 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.

To build this circuit, we will need 3 main components. We will need a temperature sensor IC. The one we will use in this project is a LM34 temperature sensor IC. We will need an LCD display. The type we will use is the popular HD44780 LCD. And we will need a microcontroller to get the readout from the sensor IC and then transfer the readout to the LCD>

To be successful building this circuit, you should know how to connect temperature sensor ICs and how to wire a HD44780 to an Arduino.
