Introduction: HabitSpark 7
When you want to build a habit or achieve a goal, you can use this box I designed to help! Our box has 7 switches, and each day you complete a task, you can flip one switch. After successfully completing tasks for 7 consecutive days, the box will release colorful confetti to celebrate! It encourages you to cultivate your habits in 7-day cycles.
Supplies
Required Materials for the 7-Day Habit Box:
- 7 x 5mm LED Lights
- 7 x ON-OFF Toggle Switches
- 1 x 5V Electromagnet
- 1 x Balloon
- 1 x Arduino UNO Board
- Electrical Wires
- 1 x iron piece
Step 1: 3D Printing All Required Parts
3D Printing All Required Parts
Step 2: Connect the Electronic Components on the Uno Board As Shown.
Replace the servo motor in the diagram with an electromagnet. The electromagnet has two wires: connect one wire to the ground line and the other to pin 4.
