sudo apt-get install gcc
```

### Install Node-RED
[Installing Node-RED on Raspberry Pi](https://nodered.org/docs/getting-started/raspberrypi)

#### Prerequisites
Ensure npm is able to build any binary modules it needs to install.
```
sudo apt-get install build-essential
```

#### Download and installation
To install Node.js, npm and Node-RED onto a Raspberry Pi, run the following command will that download and install them:
```
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
```
Due to the limited memory of the Raspberry Pi, you will need to start Node-RED with an additional argument to tell the underlying Node.js process to free up unused memory sooner than it would otherwise.
```
node-red-pi --max-old-space-size=256
```

#### Autostart on boot
Run Node-RED when the Pi is turned on, or re-booted, enable the service to autostart by running the command:
```
sudo systemctl enable nodered.service
```

#### Check the installation
Make sure NodeRed is correctly installed by reaching the following page from the broswer of your pi : http://localhost:1880.

#### Install few nodes
These nodes will be used in Node-RED:
```
cd .node-red/
npm install node-red-dashboard
npm install node-red-contrib-python3-function
npm install node-red-contrib-camerapi
npm install node-red-contrib-gpsd
npm install node-red-contrib-web-worldmap
```

#### Import the last GUI

Import the lastest version of the GUI from https://raw.githubusercontent.com/tpollina/PlanktonScope/master/scripts/flows_planktonscope.json>

### Install Mosquitto MQTT

In order to send and receive from Node-RED:
```
sudo apt-get install mosquitto mosquitto-clients

```

### Install mqtt-paho

In order to send and receive from python:
```
pip3 install paho-mqtt
```

### Install OpenCV
