QuickStart

Setup

Components

• Arduino UNO (Atmega-328p)

• IR Emitter

• IR Receiver

• 1x4 Keypad

• Photo Resistor

• PIR Sensor

Schematic

Wire the compoments using the schematic shown below:

Arduino

Dependencies

• IRremote Arduino library

Setup

1. Load the sketch file

Using the Arduino IDE load the sketch file sketch.ino which resides in the sketch directory.

2. Verify (build)

3. Flash

4. Test

Test the setup using the integrated serial monitor by sending 3 to the target board which should result in returning the value read by the photo resistor.

Arduino Server

1. Install

To install the python package containg the Arduino server:

cd arduino_iface
pip3 install .

2. Start the server

arduino_server --serial_port <path_to_arduino_serial_port>

3. Test

cd arduino_iface/test
pytest -vv

Optionally you can install the Arduino Server as a SystemD service using the example file provided in the arduino_iface/init/systemd direcotry.

This file requires the following modifications:

Change @@__USER__@@ and @@__GROUP__@@ accordingly. You can ge this information by using the whoami command.

Change @@__PATH_TO_ARDUINO_SERVER_DIR__@@/arduino_server to the correct path where the binary has been installed. You can get this infromation by using the which rduino_server command.

To get the correct path for the serial port look for the Arduino device in the /dev/serial/by-id/ directory.

Once the file has benn modified copy it in the /etc/systemd/system/ directory and start the service using the commands below:

sudo systemctl start arduino-server.service
sudo systemctl enable arduino-server.service
