Having trouble motivating your toddler while potty training them? Well, I have the answer for you, the Potty Training Aid. After each time your toddler uses the potty correctly they push a button to celebrate their accomplishment. The Potty Training Aid will play a song and light an array of lights. This is a can be a little tricky to set-up, but if you take your time you will be able to complete this project.
Step 1: Materials
15 Male-Male Jumper Wires
9 - 330 Ohm Resistors
8 - LEDs
1 - Push Button
1 - Piezo Buzzer
Computer & Arduino IDE download at http://arduino.cc
Step 2: Hooking Up the Components
Connect the materials as seen in the pictures above.
The piezo buzzer is much larger in the digital diagram.
The Piezo Buzzer is polarized and can only be connected to a circuit in one direction.
The LEDs are also polarized and can only be connected to a circuit in one direction. I found it helpful to have all the LED anodes facing the same direction.
Step 3: The Code
Step 4: The Finished Product
Time to test your finished potty training aid. If everything is set up correctly the 8 LEDs will light up quickly and then a song will start to play.
