Step right up & test your LOVE! Invent your own carnival-style Love-O-Meter to see if you have what it takes to be a big hunk of love. Happy Valentines Day!

Duration: 30 Mins

How To Make It


Add code to arduino Bit The Arduino reads the analog voltage from the pressure sensor, and lights up the RGB LEDs depending on how high the voltage is.


Assemble circuit Attach three RBG LEDs to the output ends of the arduino. Adjust the color of the LEDs using a littleBits screwdriver. I set it to blue for Naive, pink for Puppy Love & red for Infatuated.


Add input I used a pressure sensor as the input for this project, but you can try using another Bit. Maybe a temperature sensor to measure how hot you are :) Connect a wire to the input end of the arduino to connect the pressure sensor. Use another wire to connect the power Bit.

Build housing for the circuit I found this cardboard box in the mailroom of our office. It’s a pretty simple design, but it reminded me of an arcade machine. I added a front facade, punched holes to reveal the LEDs.

Add circuit to housing I used tape to attach the arduino & RGB LEDs to the back of the machine. I then cut a slit and fed the pressure sensor through the facade.

Decorate housing I used white & red spray paint & printed out the lettering & emoji.

Test your love! How much ~feels~ do you have? It's pretty easy to get infatuated. But hey, that's love!
