Paper feeder program
The paper feeder program can be downloaded here: EdPrinter programs.
How it works
The program enters a loop and waits for infrared (IR) data from the pen controller Edison.
When IR data is received the receive data icon moves the data into a variable called ‘Data_Received’. The first If icon tests if the received data is equal to 1, if yes, then the dual drive icon moves the wheels forward for .01 seconds (event wait icon). This causes the paper to feed out of the EdPrinter. If the data is not equal to 1, then the second If icon tests if the received data is equal to 2, if yes, then the dual drive icon moves the wheels backward for .01 seconds (event wait icon). This causes the paper to move back into the EdPrinter.
To create your own printed shapes you can use this program without making any changes. The program in the pen controller Edison is the only program that needs to be changed.
Pen controller program
A sample pen controller program that draws a square can be downloaded here: EdPrinter programs.
This program is made up of four parts, one for each side of the square that it draws. First we move the pen (side 1), then move the paper (side 2), then we move the pen (side 3) and finish with moving the paper (side 4).
