Abstract:

By using AUTODESK 123D Circuits an electronic circuit is designed and tested before construction. The program allowed to visually see the operation and make quick changes to the electronic circuit. The program allowed for the design of Printed Circuit Board Design (PCB). The first part of the lab consisted of circuit simulation. A Wheatstone bride light detector circuit was designed and the simulation was used to prove changes in resistance could switch a motor on, or off with the use of a relay. The simulation allowed to change the resistance using a simulated potentiometer to control a relay. The second part of the lab PCB design was constructed. The PCB design was done in the AUTODESK 123D Circuits software. The PCB board design was a copy of the original circuit in PCB friendly design. The device had to adjusted with the correct footprint a layout to operate properly.

Introduction:

The purpose of this lab is to design an electronic circuit using the software from AUTODESK 123D Circuits and to create a correct PCB board from the software. The software allows for testing and creating circuits with basic PCB design. The lab showed us the basics of properly designing PCB board designs.

Materials and Methods:

The only equipment required for the lab was the program online AUTODESK 123D Circuits. The first part of the lab consisted of learning how to make a circuit with the program. The initial steps were creating an account, creating a file for the circuit and adding specific components. The components added into the circuit were two resistors, a 741 op amp, a photo-resistor, a NPN transistor, a relay SPDT, diode, potentiometer, and a 9 volt battery. The circuit was completed by adding all of these components onto the breadboard view of the circuit shown in Figure 1. The program then...
