Hardware

An embedded system is a computer system. It is embedded as part of a complete device often including electrial or electronic hardware and mechanical parts. Hardware is all physical components or equipment. They need software to be operated, but they are distinct elements.

This project takes advantage of the following hardware:

Microcontroller

Tiva C Series LaunchPad

EK-TM4C123GXL

4x4 Keypad

ECO.16250.06.SP

LCD

PWB20171-CEM

Distance Sensor

LIDAR

VL53L0X

Temperature Sensor

T101

SOT23-6

(EEPROM)

Circuit Diagram

A circuit diagram is a visual display of an electrical circuit using standard symbols. Drawing the circuit schematic is very useful before starting wiring all the components together because it provides a guideline on how to assemble them.

This schematic was drawn using KiCad software.

Note: In this schematic there is still one component missing.

Circuit Assembly

When assembling any circuit, organization is the key for a good assemble practice, avoiding chaotic circuits. In this project, was attempted to keep all the connections clear and easy to follow on the breadboard.

Note: In this picture not all connections are done, and there is still one component missing.
