In this DIY session we are going to use a 32×16 LED dot Matrix display module which is also known as P10 LED Display Module to display a scrolling text by using Arduino UNO. P10 modules can be cascaded to build any size of the advertising board.

So in this project, we build an Acoustic Home Automation Device in which we will be able to control this smart device without using any wireless connections like Wi-Fi or Bluetooth. We will use Actions for Google and Dialogflow to build a test application for our Google Assistant to make it play encoded audio (Chirp). This audio will then be captured by the Arduino nano BLE sense board running the Chirp Arduino Program, based on the message encoded in the data the Arduino board could perform any action like toggling an AC load controlling the RGB LED, etc. It might sound like a lot, but it is relatively simple.
DIY Raspberry Pi Gaming Console using RetroPie
Raspberry Pi is an amazing credit-card sized computer most suited for IoT based applications and online servers like Print server, webserver, Media server. Many types of custom ROMs and custom operating systems are available for Raspberry Pi and you just need to burn the custom ROM on SD card and insert it in Raspberry Pi. Like Windows 10 and Android can be easily installed on Raspberry Pi.
There is a Python library to access all capabilities of an official WhatsApp on Raspberry pi – Yowsup. It enables you to use your WhatsApp account to exchange messages without the original app with your contacts. This library allows the user to create a full-fledged custom WhatsApp client on Raspberry Pi.

In this post we will build Raspberry Pi based Bluetooth Speaker by fusing the power of A2DP, Linux and audio codec to stream the data packets from an audio source to an audio sink wirelessly. To do so we are going to hack a little bit of Linux system and write a piece of code in bash and python and we will be in business.
