Cross-platform builds

[bytemebro]

Has anyone ever brought together an Arduino, Raspberry Pi, and ESP8266 in one project? I’d love to hear how you managed to get them all to work in harmony

I'm curious too, so I did a little digging.

Here’s a simple way to visualize a cross-platform project combining Arduino, Raspberry Pi, and ESP8266:
+----------------+
| Arduino |
| (Sensors / |
| Actuators) |
+--------+-------+
|
Serial / UART
|
+--------v-------+
| Raspberry Pi |
| (Processing, |
| Dashboard, |
| Logging) |
+--------+-------+
|
Wi-Fi / MQTT / HTTP
|
+--------v-------+
| ESP8266 |
| (Remote Control|
| & IoT Devices)|
+----------------+

Workflow:

Arduino reads sensors and sends data via USB serial to the Raspberry Pi.

1. Raspberry Pi processes the data, logs it, and updates a dashboard.
2. Raspberry Pi sends control commands via Wi-Fi (MQTT or HTTP) to ESP8266-connected devices like smart plugs, lights, or relays.
3. ESP8266 executes the commands and can also send back status updates.

honestly, I used a similar stack for an environmental monitor. The key is to make the Raspberry Pi the master and everything else a dedicated slave.
Don't try to make them all equal partners! Assign distinct roles.

Great tip. Keeping the Pi as the master really does make sense.
