Description

This example uses the DigitalOutput component to control the LED attached to the Arduino board on pin 13. It uses a BooleanPulse from the Modelica library to produce an On/Off signal that is fed into the DigitalOutput component. This will make the LED attached to the pin blink.

You can go ahead and add more LEDs to the board as shown in the following figure. This will require you to add one more DigitalOutput component to control the LED on pin 9.

Description

This example uses the AnalogOutput component to change the light intensity of an LED. AnalogOutput uses the Arduino function 'analogWrite', which produces a PWM (Pulse-Width Modulated) signal. This type of signal can be used to directly control the LED intensity. The following figure shows the connections.

You can see that pin A0 for the Arduino corresponds to pin number 14 for the Firmata. For other boards, the pin numbering may vary.

Run the simulation and move the potentiometer. You should see that when the position of the shaft is near the middle, the LED changes state.

The AnalogInput component returns a signal between 0 and 1. This value represents the voltage between 0 and the reference voltage. If you prefer to get the signal directly in volts, you need to change the 'MaxValue' property to the reference voltage, but generally it is either 5 V or 3.3 V.

This example shows how to control a servo by using the Servo component. You can find the diagram in the following figure.

For this example, it is recommended to use an external power source to provide voltage for the servo. This is because the power from the Arduino may not be enough to supply the servo. If you are not sure how to connect your servo, take a look at the reference in the Arduino Playground (http://playground.arduino.cc).

Description

This example is a simple ON/OFF controller and can be used for either heating or cooling. It uses an LM35 to read the temperature, and based on that temperature, the controller switches a relay on or off. You can attach a fan or a heater to the relay, depending on the operation you want to perform. You can find the diagram in the following figure.
Note: You need to be careful when using relays that control electrical equipment using AC voltage, because an incorrect connection may damage your board.

This changes the sampling interval limit from 10 ms to 1ms. You have to consider that this change is possible because the Teensy board can run up to 96 MHz. If you change the sampling interval, it is necessary to change the simulation setting in SimulationCenter to 1 ms, as shown in the following figure.
