Simulation Software

Proteus 8 Professional

Use this page together with the local project PDFs and diagrams when rebuilding the circuit in Proteus. The device mapping, warnings, and install notes are based on the project brief and the supplied component sheet.

For CPUT students only. Do not share outside the institution. Never click Check for Updates after installation, because the license copy is version-locked and can break when updated.

Download And Install

Download Proteus 8 Project brief PDF

1Extract the ZIP archive to a local folder before running setup.

2Launch setup.exe and complete the installer.

3Open license.txt and copy the provided license key.

4Paste the key when Proteus starts, or use Help -> Licence Manager if the prompt does not appear.

5Create a new project from File -> New Project and start by validating each stage independently.

6Keep the detector, counter, and status-control stages separate until each one behaves correctly on its own.

!Do not run Check for Updates. This installation is version-locked.

Reference Set

Local Support Material

These project files sit inside the site folder now, so the simulation notes can be opened side by side with the schematic diagrams while rebuilding the circuit.

Use the high-resolution full-system schematic as the top-level Proteus reference.

Component Search Mapping

Proteus search term	Real component	Notes
40110	CD40110BE	Search exactly 40110
7SEG-COM-CAT-GRN	Common cathode display	Use CAT, not CAA
IREMITTER + PHOTODIODE	TCRT5000 equivalent	Education license workaround
7408	74LS08 quad AND gate	Also appears as [7408]
INVERTER	74LS04 hex inverter	Generic inverter maps correctly
NE555	NE555 timer	22k ohm and 20uF gives roughly 1Hz
G2RL-14-DC5	DPDT relay 5V	Any 5V DPDT relay works in hardware
2N3904	2N3904 transistor	BC548 can be used as an alternate
1N4148	1N4148 diode	Use across the relay coil

Device Library

These names are the ones that matter in the Proteus library for this project:

Common cathode displays only. Do not use common anode displays for the CD40110BE stage.

Each display segment needs its own 330 ohm current-limiting resistor.

Call Communica ahead if you need a physical CD40110BE for the final build.
