- Concept
For this project, I chose the feeling of being in a rush, I wanted to make something that would help those who are constantly stressed to take things slow. This armband has a photoresistor that is used as a proximity sensor which will use sound and light to let the user know when they’re about to hit something/someone. The sound and lights become louder and brighter the closer the sensor gets to the object. It also used a motion sensor that will make a sound when the person is going too fast.
- Objective
The objective is to try to make people be more careful, the city can be very fast-paced and everyone seems to be in a rush which can cause accidents.
- Process
- Diagram
The first thing I did was the circuit diagram.
- Testing
Tested the circuit using alligator wires.
- Code
Made the code and tested it multiple times using the wires.
- Parts list
- Conductive thread
- Photoresistor
- 10k resistor
- Felt
- Thread
- Circuit Playground
- Final Prototype
- Reflections
One thing I would’ve done differently was the use of a different fabric, something that would allow me to test the motion sensor with the armband without the photoresistor moving around and triggering the proximity sensor.
