# EES Project
## v.0.01
A communication interface between an Arduino and a host machine over a serial connection.
## Features
- Establishes communication over serial interface
- Able to send and receive data encoded in ASCII format
- Arduino can handle up to 6 LDRs and can return their reading
- Each sensor is identified using a unique identifier to send and receive data
- Program contains database of sensors and can handle incorrect UIDs
## Usage
Import the file containing the models
```python
from models import Arduino, Sensor
```
Create an instance of a serial connection to the Arduino
```python
arduino = Arduino()
```
This creates an object with the following attributes:
|attr| value|
|--|--|
|port|`/dev/ttyACM0` |
|baudrate|`9600`|
|bytesize|`8`|
|timeout |`2`|
|stopbits | `serial.STOPBITS_ONE`|
If any of the attributes need to be changed change the instable variable. Eg. to change the port:
```python
arduino.port = "/dev/ttyACM0"
```
Create and add to the array storing all of the sensors
```python
ldrs = []
```
To initialise a sensor:
`main.py`
```python
ldr = Sensor(1, arduino)
```
`1` is the unique id given to this sensor. This will be used to identify the sensor. This **must** be a unique id.
`arduino` is the `Arduino()` object created earlier. This tells the program where to communicate about the sensor.
Say for example the sensor is attached to pin A5.
`arduino_code.ino`
```c++
int sensors[2] = {A4,A5}; # add A5 to the array
...
switch (serial_string.toInt())
{
case 1:
Serial.print(analogRead(sensors[0]));
break;
// Add your own case statement
case 2:
Serial.print(analogRead(sensors[1]));
break;
...
```
To get a reading from a sensor
```python
print(ldr.getReading())
```
To read what is currently in the serial buffer simply do
```python
arudino.readBuffer()
```
Close the connection:
```python
arduino.closeConnection()
```
