Project description

3. Sending data from Arduino. Now let's leave Node-red aside for a bit and let's prepare the arduino to send the data. For this implementation, the CPB Mini board was used, together with the W5500 ethernet shield. The CPB Mini has an ATmega1280, so it behaves like an Arduino mega. The following figure represents the topology of the system, the CPB communicates over ethernet with the modem that sends data via wifi to Node-red. In the following table we can see the pins that were used for communication with the ethernet shield, it is worth mentioning that from these we can only change the Chip…
