Demos

Demo 1: Digital Input

The first demo introduces you to the digital input capabilities of the Arduino Uno platform. Setup the circuit and press Start to capture switch operation at the connected button.

Circuit

For this demo you have to setup the electric circuitry as depcited below.

First, connect a 220 Ω resistor R₁ to the 5V pin on the left side. Then connect the resistor to the switch S₁ and to the digital input pin with the number 2 on the right side of the connectors of the Arduino Uno, as shown in the left picture above. Finally, connect the other pin of the switch to one of the GND pins of the left side of the connectors of the Arduino Uno.

Demo Application

Use the left button to start and deploy the model to a (locally) running ARE instance, and start to capture push button (S₁) activity.

Demo 2: Digital Output

The second demo introduces you to the digital output capabilities that are included with the Arduino Uno platform. Setup the circuit and press the buttons in the application section.

Circuit

For this demo you have to setup the electric circuitry as depicted below.

First, connect a 220 Ω resistor R₁ to the digital output pin with the number 2 on the right side of the connectors of the Arduino Uno, as shown in the left picture above. Then connect the anode of the LED D₁ (positive) with that resistor. Finally, connect the cathode of the LED (negative) to one of the GND pins on the left side of the connectors of the Arduino Uno.

Demo Application

Use the left button to start and deploy the model to a (locally) running ARE instance. Afterwards, press the buttons LED On and LED Off to turn the LED on and off, respectively. The AsTeRICS model (.acs) is started and commands are passed through to it, in order to toggle the LED.

Demo 3: PWM

The third demo shows you how to use the PWM capabilities of the digital outputs of Arduino Uno to dim a LED light. Setup the circuit, and in the application section below, choose the desired Duty Cycle and press the buttons in the application section.

Circuit

For this demo you have to setup the electric circuitry as depcited below.

First, connect a 220 Ω resistor R₁ to the PWM pin with the number ~3 on the right side of the connectors of the Arduino Uno platform, as shown in the left picture above. Then connect the anode of the LED D₁ (positive) with that resistor. Finally, connect the cathode of the LED (negative) to one of the GND pins on the left side.

Demo Application

Use the left button to start and deploy the model to a (locally) running ARE instance. Afterwards, press the buttons LED On and LED Off to turn the LED on and off, respectively. You may change the value of the slider Duty Cycle as you wish. The AsTeRICS model (.acs) is started and commands are passed through to it, in order to toggle and dim the LED.

For this demo you have to setup the electric circuitry as depcited below.

First, connect a 100 kΩ resistor R₂ to the digital output pin with the number 2, on the right side of the connectors of the Arduino Uno platform, as shown in the left picture above. Then connect the resistor with a 10 µF (electrolytic) capacitor C₁ with that resistor. Additonally, connect the positive side of C₁ with the analog pin with the number A0, on the left side of the connectors of the Aruindo Uno. Finally, connect the negative side of the (electrolytic) capacitor to one of the GND pins on the left side.

Demo Application

Use the left button to start and deploy the model to a (locally) running ARE instance. Afterwards, press the buttons Set Pin 2 and Reset Pin 2 to turn pin with the number 2 on and off, respectively. The AsTeRICS model (.acs) is started and commands are passed through to it.

Demo 5: Servo PWM

Circuit

For this demo you have to setup the electric circuitry as depcited below.

Servo motors, used for the construction of models, usually have connectors with three pins (power - control - ground). Connect the power pin (red) of the servo motor with the 5V pin on the left side. Then connect the control pin (yellow, orange, white) of the servo motor with the PWM pin with the number ~3 on the right side of the connectors of the Arduino Uno platform, as shown in the left picture above. Finally, connect the ground pin (brown, black) of the servo motor with the GND pin on the left side.
