For young children, a toy ambulance can create a feeling of joy than only a toy can make. In this intractable, I will show you how to make one.
Step 1: Build the Buzzer Circuit
This circuit involves a switch, battery, and buzzer in series. It is not very complicated.
Step 2: Light Circuit
Build an independent circuit with a switch, battery, and LED.
Step 3: Frame
Build a decent-sized frame. This will house your two circuits. Leave it open for the time being.
Step 4: Embed the Circuits in Your Frame
Simple enough. Hot glue and tape work best.
Step 5: Attach Wheels
Glue wheels (or things that look like wheels) to the bottom. An ambulance is not an ambulance without wheels.
Step 6: Decorate
Make your construction look good. You're done!
