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.

Arduino Bluetooth Wireless Communication

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

For a project I’m working on, I was searching for a method of sharing information between the Arduino and a Raspberry PI and Bluetooth came to mind. So, I start exploring.

Here’s a small example of a Wireless connection between Arduino and an Android Phone using Bluetooth.

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.
