Build your circuit: power + dimmer + servo. Press the servo hub onto the servo. Press the servo into the servo mount from the side and screw in.
Press adhesive shoes onto your circuit and servo mount. Connect the mechanical arm to the servo hub with screws. Attach the moving image to the mechanical arm with tape.
Set servo to swing mode. Test your circuit.
Peel the red back from your adhesive shoes and press the circuit and servo mount onto your collage. Attach the battery with two glue dots. Mount your background image to the walk and tape all four corners down well.
Now you have an eye catching display! Control how fast your animated image moves by twisting the dimmer knob.
