Lumale – Traffic light system

In a week of exploring different electronic components and circuits to get a basic level in the materials of electronics, we created a system that simulates a functioning traffic light. By pressing the car onto the circuit, the traffic light will go on and cycle through the green, yellow and red colored LED’s.

By using an oscillator, a counter chip can be controlled that switches the lights in a certain time period and a buzzer is connected in a way that it will go off when the green light goes on.

As a first iteration, we also built a functioning pressure sensor connected to an oscillator to create a prototype that makes a sound through a simple piezo speaker every time there is weight on it. The sensor was sewn into fabric so it can be used on furniture or clothing, for example this type of circuitry could be used to scare a dog off a couch.
