Bluetooth communication between Raspberry PI and Arduino

This post is part II of a III part series of posts related to Arduino and Raspberry PI Wireless Bluetooth communications.

  • Part I
  • Part III (coming soon)

In another post, I’ve shown how to communicate with Arduino through Bluetooth. Arduino is a very nice platform for electronics, but sometimes, we need a full computer for more expensive workload.

Here, I’ll show how to share information between the Arduino and the Raspberry PI. Imagine that you have the Arduino taking measurements and send them to the Raspberry PI to work on the data – a web server for example.

Give your Raspberry PI the power of Speech with Adafruit’s max98306

For a project I’m working on, one of the objectives is that the RPi be able to “speak” – just to have some fun.

The RPI can output audio through HDMI and the 3.5mm audio jack. Since I’m going to use the RPi for a small robot, the HDMI audio capabilities are of no interest. So, it only leaves the 3.5MM audio jack, but there’s a problem. The audio is not amplified. For some headphones it’s fine, but for a talking robot, the audio volume is just to low.

Transferir imagens (tiradas com a camera do PI) usando Xbee e as funções serie do Python

Agora que já sabemos como programar os XBees em Python, vamos subir um pouco e em vez de passar caracteres pelos XBee, vamos passar dados, neste caso uma imagem.

Vamos usar a camera do PI para tirar a foto e posteriormente enviar para outro computador.
