Standard Genie E18 Circuit
Like the Genie CO8 the Genie E18 is a microcontroller.
The Genie E18 has 5 input pins.
3 of the input pins can be used to connect either digital or analogue input components.
2 of the input pins can only have digital input components connected.
The Genie E18 has a total of 8 output pins meaning that a large number of outputs can be connected to this microcontroller.

This is a basic E18 circuit.
This basic circuit allows the microcontroller to be connected to a computer.
The microcontroller communicates with the computer via the ST (status) pin.
The compoter send the data to the microcontroller via the PR (programming) pin.
Pin 4 is the reset pin. You can connect the circuit without the PTM reset switch, however the pin must be pulled high (connected to the positive power rail) via a 4.7k resistor.
The diode is in place to protect the circuit from reverse polarity (the batteries being put into place the wrong way around – this can damage the microcontroller.

One of the easiest output components to add to the Genie circuit is a Piezo.
No other components are required and the connection is very straight forward.
You can choose the piezo from the gallery, however as the component will normally have flying leads and therefore you may find it easier to simply use two pads and a strain hole. You can simply add two pads and a strain hole if you want to.
