Team - Het, Sammy & Sohee
Working with your group from last week, enhance or transform your homemade switch using something you’ve learned from this week!
#1 Addition of a traffic signal
We received faculty feedback suggesting that they would have loved to see some form of actual Green Light incorporated in our design. We decided to remove the heart and add a traffic signal - since it is originally inspired from a traffic signal - If the signal is green you are allowed to walk. Inclusion of traffic signal gave us an opportunity to play with 2 lights - red and green. We decided to switch the lights from red to green once the eye-contact is established.
#2 Improving the switch
Our original switch, while was functional, lacked sophistication. It had sticks attached to the dolls' bottom surface covered in aluminium foil, requiring them to touch for circuit completion. This design had numerous moving parts, leading to occasional failures due to poor contact or loose foil wrapping.
We decided to use an Infrared (IR) Sensor to use a switch. An IR sensor has 2 components: the IR transmitter & the IR receiver. The IR transmitter continuously emits the IR light and the IR receiver keeps on checking for the reflected light. If the light gets reflected back by hitting any object in front it, the IR receiver receives this light. This way the object is detected in the case of the IR sensor.
We attached the IR sensor to one doll and integrated it with an Arduino UNO board.
#3 Visual enhancement
We improved the aesthetics by adding flower petals to the box's surface and decorating the dolls to conceal the IR sensor.
