My Interactive Project was a continuation of my creative switch
project. My creative switch project was a toy car with LED headlights (see picture below). 

For my Interactive Project, I created a miniature environment for this toy car. The miniature environment for this toy car consists of an intersection with a key interactive element: the Arduino powered stoplight (pictures below). 

2. Use sandpaper to shape the foam into the desired form. 

3. Glue the together and then paint/decorate the stoplight.  

4. Time to incorporate the Arduino components – 

– Arduino UNO

– 3 Leds

– 3 resistors 330oms

– Ultrasonic distance sensor

– Jumpers

4. Create the code. 

Let’s take a look at the finished product!
