With an update in March 2019, Valve introduced the Steam Link Anywhere update that allows one to stream across the internet, though the performance of the streaming will be strongly affected by the bandwidth and latency between the personal computer and device with Steam Link. Prior to March 2019, both the personal computer and the Steam Link hardware device or mobile device using Steam Link software had to be on the same internal network. In this setup, the device acting as the Steam Link (the hardware unit or the mobile device in software form) enables a game controller connected to it to be used to control the game over the connection to the home computer. Steam Link, whether in hardware or software form, supports the streaming of content from a personal computer running Steam to the video device (a connected television or monitor for the hardware unit, the mobile device's screen for the software version). Valve discontinued the Steam Link hardware device in November 2018, in favor of supporting its software-based Steam Link application for mobile devices and smart televisions, as well as providing Steam Link as a software package for the Raspberry Pi microcomputer. Steam Link was originally released as a hardware device alongside the debut of Steam Machines in November 2015. Everything is housed inside of a case that any of the best 3D printers could create.Steam Link is a hardware and software product developed by Valve Corporation for streaming Steam content from a personal computer or Steam Machine wirelessly to a mobile device or other monitor. A ULN2803 Darlington driver board is used to control the LEDs. The arcade buttons feature 5V LEDs that are crucial to the game core functions, so you can’t substitute these for ones without LEDs. Any model of Raspberry Pi Pico can be used, including some other RP2040 based boards. It doesn’t take much processing power to handle these games, so Watkiss is using a Raspberry Pi Pico. Players must hit their button as fast as possible when the light illuminates.

The second game is a reaction game that can support up to four players. The button pressed first will illuminate, signifying who gets to answer the question.

When a player thinks they have the right answer, they must slap (or gently press) their button. First, a person reads the question to the two players. The first game the project features is somewhat of a quiz buzzer.
