ECET380 G12

This is a demonstration of how to design a stage that can represent the changing of scenery on stage. In this example, we changed the setting on the stage with a moon and a sun. Hope you Enjoy!

In this step, you are going to be using the Atmega2560. Plug the USB cable that came with the controller into the computer and Atmega2560. In our example, we used the Atmel software to download the code to our controller. You may use another program or code but we have given ours as an example in the pictures. Download and run the code at the top of the screen onto the controller then move onto the next step.

In this step, we are connecting the pushbuttons to the input of the microcontroller and wiring the pushbuttons up on the breadboard. The image shown shows both pushbuttons are grounded to the controller on one side while the other side is connected to the Atmega2560. A capacitor is optional and can be put in parallel with pushbuttons to produce a better response when pushing the buttons. A schematic is shown to add the connections.

In order for the stepper motor to work you need to add power to it. We can use the 5V and GND pin from the Atmega2560. After the motor has received power we can connect the output of the controller to the stepper motor as shown in the pictures. This is the last step for the electrical connections. If the code is downloaded properly and all the connections were made right you should be able to rotate the motor clockwise and counterclockwise with the pushbuttons.

Pre-drill holes just a little bit smaller than the screws into the boards. One hole on the end of each board and then one on the opposite end on the side towards the top. (If gluing skip this step)

You will then attach the two vertical supports with a screw or glue through the bottom of the balsa wood and into the bottom of a piece of 1” X 2”. Roughly 3 inches from the edge of the balsa wood.

Run the fishing line through one pulley then around the next pulley and back to the first pulley. One end of the line will attach to the motor and the other to the fishing weight acting as a counterweight.

Cut small holes in the props and attach them to the line.
