![]() ![]() Most games I tried were bad, some were too heavy to run smoothly on Raspberry Pi, but I selected 10 games, across different genres, that run quite well and are worth trying. I’ve had the opportunity to try many games available and I will share a shortlist with you here. That’s why I wrote this article! Many games are available in Raspberry Pi OS repositories. But maybe you aren’t a serious gamer and use it to take a break sometimes and play a mini-game on it. Many users (including you?) initially bought it to install Retropie or an alternative and play old games on it. We also set the context here.One of the most common uses on Raspberry Pi is gaming. Once you press the pound key it downloads and plays the recording using the default audio device! Understanding the CodeĪll the code for the RELAY Consumer is in the consumer.js file.įirst, we import the SignalWire Realtime API and create a new RELAY voice client using the credentials from the environment file. It will play a text-to-speech prompt to tell you to record a message after the beep and press the pound key. SIGNALWIRE_PROJECT_KEY=Ĭall the phone number configured to the context for this consumer. env file with your credentials and the verified phone number. git clone Ĭd signalwire-relay-examples/node/remote-announcementsĬreate a. Running the consumerĬlone the repository and navigate to this folder. Your Raspberry Pi should now be connected to WiFi, accessible through SSH, and have NodeJS installed before proceeding to the instructions to run the RELAY Consumer. In iTerm this can be done with the following command: ssh Run the following commands to install NodeJS on the PiĬurl -sSL | sudo bash - sudo apt install -y nodejs Create an SSH connection to the Pi with the user credentials and hostname created during the first step.Open a terminal application such as iTerm or PuTTY.Insert the SD card into the Pi, connect it to 5V USB power to turn it on. ![]() Plug in a speaker of your choice to the Pi’s 3.5mm audio jack.(The common default user/password is no longer included for security purposes) Be sure to follow the Advanced Options to add your WiFi credentials, set a hostname, enable SSH, and create a user. Use the Raspberry Pi Imager to install the Raspberry Pi OS Lite image to an SD card.This process is headless, meaning you only need to power your Pi and won’t need a monitor or keyboard. The following instructions are the steps we took to install an operating system to an SD card, configure WiFi and SSH access, and install NodeJS. If you prefer, you can follow the general getting started instructions for the Raspberry Pi from the official documentation. To run the example a SignalWire Project ID and API Token are required. Once your account and inbound phone number are created, you need to edit the inbound phone number to forward calls to the context used by the RELAY Consumer - in this example, speaker. Try experimenting after following this guide to see what else you can build! For example, you call a number and are given some dial pad options to turn on the lights, get sensor information, or initiate party mode. Skipping that extra step opens the door to doing things like running an interactive voice response (IVR) that can interact with physical peripherals available to the Pi. The alternative would be your consumer is running in the cloud and you would have to send the recording result to the Pi using some IoT messaging platform. Here we use it so the Pi has immediate access to the call recording. Since the consumer can run directly on the Raspberry Pi, you can run all your call or SMS automation right at the edge. ![]() This context can be used to direct phone numbers to the consumer application in the event of voice calls or messaging. It can register with an arbitrary context. A consumer is a class that encapsulates the main connection and call handling features of RELAY. This example demonstrates running a SignalWire RELAY Consumer. Raspberry Pi is great for IoT projects or when you need a computer for a very specific purpose. While this NodeJS example can run on any machine with a speaker, we’ve run it on a Raspberry Pi, a low-cost single-board Linux computer. To dive deeper into RELAY, check our in-depth getting started guide. It can run in the browser or server side. SignalWire RELAY is an advanced interactive communications API that lets you build powerful applications using voice and SMS. Using SignalWire RELAY you can call your WiFi-connected Raspberry Pi over the phone and leave messages for it to play on a speaker. ![]()
