The whiteboard activity allows kids to draw on a whiteboard and control a DMX light by turning on and off the red, green, and blue channels separately and see how those colors shining on the board affect the colors in the drawings they made. Some colors change while others can seem to disappear altogether. They can turn on multiple at a time to mix colors, all 3 switched on will create white. Looking at the DMX light (though not directly) shows which RGB channels are on, allowing the kids to see actual lights mixing into colors.

Step 2: Make a Stand for the DMX Light

We made a 10x 8 x8 inch box. This would be a stand for the DMX light that shines on the whiteboard

Step 3: Make the Wooden Stand for the Whiteboard

We used hardwood for the surroundings and MDF was glued to the back of the whiteboard so we can thread the standoffs into it for the Arduino and the power supply

Make sure you drill holes for the DMX and the power supply at the back.

The hardwood was of height of 2.5 inches. This was to make sure everything had enough clearance
