I have made some progress with the "Kerbal Space Program 2 celebration machine" and have a sequence of actions to perform, and have had success connecting to google.com with the RobotDyn W5500 Ethernet module. However, when I put store.steampowered.com as the address to connect to, I get a "The requested URL "[no URL]", is invalid." error, and if I specify any specific page for a game, for example "Kerbal Space Program 2 on Steam" the connection doesn't happen at all("connection failed" is printed). Also, If I add an SD card module (Virtuabotix SD Card Reader) the connection fails in a similar way to if I tried to connect to Kerbal Space Program 2 on Steam . I do have the chip select pin off to the side, so when the connection is being made, the chip select pin only connects to the Ethernet module and not the SD card module. Pin 10 is connected to only the CSN pin on the Ethernet module, pin 11 is connected to MOSI on the SD card module and MOSI on the Ethernet module, pin 12 is connected to MISO on the SD card module and MISO on the Ethernet module, and pin 13 is connected to SCK on the SD card module and CLK on the Ethernet module. I have an SD card module connected so I can play the KSP theme song through a speaker, and I am trying to connect to store.steampowered.com to check if Kerbal Space Program 2 has been released. This is the goal of this project: The arduino uno is supposed to constantly check the page "Kerbal Space Program 2 on Steam" for the text "Buy Kerbal Space Program 2". If it can't connect to the site, make a RGB LED constantly flash red. If it can connect to the site but can't find the text "Buy Kerbal Space Program 2" make the RGB LED a solid white color. If it does find the text "Buy Kerbal Space Program 2", then move a servo motor which will pull a party popper, play the KSP theme song, and make the RGB LED cycle between red, green, and blue. The theme song will stop when it reaches the end, and the LED will continue to cycle between the colors. If I can get this to work, then I would like to know what code I would type to search the page "Kerbal Space Program 2 on Steam" for the text "Buy Kerbal Space Program 2" and activate a function if the text is found.
Many SC-card-readers need a 'fix' to disconnect properly when not 'talked to'.
The fix can be found in this forum. SOLVED. Nrf24 (Mirf lib) + Micro SD-card works OK together - Storage - Arduino Forum
