M.ISMAIL - Week 7

Week 7 Assignment:

Program Arduino UNO to read signals from multiple input components to control multiple action components using Arduino C (Text Code).

IDEATION

We tend to set in bad posture for long periods of time without realizing, so the goal was to create a device that alerts by the users when leaning forward as a reminder to fix their posture by emitting a sound and light.

It can also be used to reduce road accidents caused by sleeping drivers.

Design/Preparation Process

Tools and Components Needed:

Autodesk Tinkercad for simulation of the circuit.

Buzzer

LED

Arduino Uno

Breadboard

Jumper wires

Switch

Mercury tilt sensor

Crocodile wires

Development / Implementation Process.

Started by connecting the components on tinkercad for simulation.

Tilt sensor & switch: pin 7 INPUTS

LED: pin 8 OUTPUT

Buzzer: pin 5 OUTPUT

Code to test the circuit.

Connecting components to Arduino UNO

Sensor (INPUT):

S pin to 7 pin

middle pin to 5V

-Ve pin to GND

Switch (INPUT) to pin 7 and GND

LED: pin 8 OUTPUT

Buzzer: pin 5 OUTPUT

Cardboard enclosure

Overcoming Challenges

By replacing Arduino UNO with mini the enclosure can be more convenient for user prototype testing as it's not yet suitable to be used due to the size.
