For Question 1, you will be required to implement an electronic circuit of your design on the

TinkerCAD browser software (Tinkercad.com) that you have been using throughout the

coursework exercises; you will need to take screenshots of your working circuit and add

them to your document, it is suggested you use Snipping Tool or other screen shot tool to

do this.

Technicians or academic staff or invigilators present during the exam window, will only be

able to respond to personal or technical problems, they will not be able to help you debug a

circuit or help with questions (other than if a question has an error in it).

Mobile phones will not be permitted during the exam. You must use the computer provided

and log in with your UWE account (unless you have reasonable adjustments) but it must be

connected to the UWE Wi-Fi network. IT services record all websites and internet traffic

used during the exam, and should the computer be used for communication or accessing

contract cheating websites during the exam, they will pass this information to the

department's Assessment Offence Advisors for investigation.

Q1 (50 total marks)

You are tasked with designing an electronic system for detecting a force of over 2.48 Newtons.

The system must alert a user to a force of over 2.48 Newtons applied to an appropriate sensor, by

turning on an LED. The LED must remain off below this force. All resistors used must be from the

series. This work is to be performed on TinkerCAD

To fully answer the question, you must provide:

Full calculations for all components you use, clearly indicated what you are calculating.

A screenshot of the TinkerCAD circuit with it in the LED off state (clearly showing the forces

on the sensor).

A screenshot of the TinkerCAD circuit with it in the LED on state (clearly showing the force

on the sensor).

A written explanation of how the circuit works.
