Step 3: Assembling the Piano
Now use your hot glue gun to secure the LEDs and buttons in place. Lay your popsicle stick across the bottom of the three buttons and hot glue it firmly in place. Now, smother the buttons with hot glue so when you press each button, the container stays stable.
To complete this project, we will have to insert our batteries into each key. Take the wire soldered to the negative lead of the LED and hold it on the negative side of the battery. Hold the wire coming from the button and hold that on the positive side of the battery. Electric tape around the whole battery making sure the wires stay attatched to the battery. Do this to each key and test each one by pressing the buttons on the top of the container.
