Scissors, Ruler or Soft Tape Measure, & Bead Board
Plan out your circuit
Plan out your circuit using alligator clips. Connect the negative pad of the heart LEDboard to the batteryboard and the positive side of the Heart LEDboard to light sensor. Your batteryboard should have three connections like the picture.
Build the base
Build a round base of your turtle or another animal of our choosing. Attach the components onto the base of your turtle (or another animal of our choosing). Make sure to place the light sensor face down on the underside of the turtle.
Connect your circuit
Connect the circuit using conductive tape.
Cover the conductive tape with the shell of the turtle.
Build your animal
Add the legs, head and tail to the turtle to make it complete.
Test out your project
Plug in a battery and place the turtle on the table. The light sensor reacts as a switch, which means if you cover the sensor so it senses dark, the heart LED will light up!
