797d18af bc8d 4436 862b 35630846e8ca

CLIP FOUR ALLIGATOR CLIPS TO THE EARTH PAD, LEFT ARROW PAD, RIGHT ARROW PAD, AND SPACE/CLICK PAD.

STEP 4 :

TURN POWER ON AND TEST YOUR CIRCUIT.
  • Touching the loose end of the alligator clips on the LEFT ARROW pad, RIGHT ARROW pad, and SPACE/CLICK pad, while touching the loose end of the alligator clip on the EARTH pad should light up the respective LEDs on the Makey Makey Bit.
  • Touching the alligator clips connected to the SPACE/CLICK pad and EARTH pad should light up the bargraph and buzz the buzzer.

STEP 5 :

ATTACH YOUR ALLIGATOR CLIPS TO YOUR CONDUCTIVE CONTROLS. We used carrots for “LEFT ARROW” and “RIGHT ARROW”, and a red pepper for “SPACE/CLICK.” “EARTH” is attached to a piece of foil.

You just created your own game controller! How effective is it?

STEP 10 : HOW IT WORKS

771451cf 8652 4e5d 83e3 6d70578b7163

  • The POWER Bit provides electricity to the circuit.
  • The MAKEY MAKEY Bit sends an ON signal when LEFT ARROW, SPACE/CLICK or RIGHT ARROW are connected to EARTH This happens when your hands bridge the gap between the foil and your vegetables, allowing electricity to flow through the circuit. This sends a command to your computer keys through the micro usb cord, and sends a signal to the rest of your circuit.
  • The BUZZER sounds when it gets a signal from the Makey Makey Bit.
  • The BARGRAPH lights up when it gets a signal from the buzzer.

STEP 11 : REMIX

TIME TO CUSTOMIZE! TRY THESE IDEAS, THEN GET CREATIVE WITH THE STUFF AROUND YOU TO COME UP WITH YOUR OWN.

  • SWITCH THINGS UP AND USE YOUR FOOD TO CONTROL AN ONLINE INSTRUMENT. Check out the Makey Makey website for digital bongos, pianos, and more!
  • PLAY WITH YOUR FOOD! Use other foods like carrots, eggplants, and even peanut butter to change up your game experience.
  • ADD SOME EXTRA VISUAL EFFECTS. Use a servo to animate a paper cutout of your favorite video game character, and have it cheer you on in your adventure.

STEP 12 : SHARE

EXPERIMENT WITH DIFFERENT FOOD CONTROLS, AND DRAW A FOOD PYRAMID OF WHAT WAS MOST EFFECTIVE. Share your results on the littleBits Invent app!
