You are tasked with designing an electronic circuit system for detecting a bend of over 90

degrees.

The system must alert a user to bending (flex) of over 90 degrees applied to an appropriate

sensor, by turning on a buzzer to create an audible sound at 500 Hz [Note, please MUTE

your computer before you simulate] The buzzer must remain off below this force. All

resistors used must be from the E12 series. This work is to be performed on TinkerCAD.

Note that use of programmable elements in TinkerCAD such as the Arduino is not suitable

and will not get any marks.

To fully answer the question, you must provide:

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

calculating.

the full circuit including the sensor).
