This Donation Station at the Lincoln Park Zoo accepts bills and coins. When a bill or coin is deposited, the running total of the contribution is displayed to the right of the acceptors. Using the yellow pushbuttons the visitor can then choose between 3 different projects to which the contribution is to be applied. The amount of the contribution is added and shown on the display for that project. Signal-Innova's GameWorks is used to get input from the bill and coin validators and the pushbuttons and send the results to the LED display modules.
