Our project attempts to provide an avenue for two people to communicate their inside jokes to each other. 




The alert system is based on the use of two sensors, Photoresistor and Force Sensitive Resistor, with a red LED as the visual feedback.


The circuit includes:

● Spark Microcontroller

● Breadboard

● Jumper Wires

● A 1kΩ Resistor

● A single color LED

● Two 10kΩ Resistor

● A Photoresistor

● A Force Sensitive Resistor



Imagine two siblings that were taught from a young age that anyone who has a mustache is a possible abductor. The idea that men with mustaches pose a higher likelihood of abducting people has become something of an inside joke to the two siblings. When they are together at the mall and see a man with a mustache they nudge each other and let the other one know about the person they just saw. They have shared a moment together that they both have a history with and share a laugh about the situation.


Or consider the tradition that many people have of when they see a vehicle with one headlight out they two race to yell “padiddle” to each other. Meaning is conveyed by the use of the term padiddle that both of the people understand, namely that they have just seen a vehicle that only has one headlight.


Our platform allows the people above to share this moment with each other even when they are not together by flashing a color of light to the other person’s device. The two people can set up one of the three colors to correspond with one of their inside jokes. 


Now, when one sister is strolling down Rodeo Drive in Los Angeles and sees an awkward looking man with a mustache, she can send a nudge to her sister on Fifth Avenue in New York and both can smile knowing that they have grown closer through the experience. This facilitates a sense of connection through the cloud even though they are separated by thousands of miles.
