1.5. Principles and Practices

Project Sketch

I want to create an interactive activity where LEDs light up in white in a certain shape, and the user has to draw the same shape. This will be done using touch sensors at specific points. When each touch sensor is pressed, the LED color will change to green. If the wrong LED’s touch sensor is pressed, the LED will blink red and the screen will say incorrect. In a way, it will be like interactive Connect the Dots. If you make contact with each dot necessary to complete the shape, the small screen in the corner will say correct. If you do not do it correctly, you will get another chance. This will continue until you get the shape correct. This project will be designed to help children learn how to write numbers and letters.
