4. Not really what I wanted. Sensors, displays, screens, motors, servos, lights, LEDs and more! Arduino UNO (2 nos.) Wrote my first "program" in 1964. Do not connect Raspberry Pi hardware directly to devices that deliver higher voltages. Remember, Linux is case sensitive. I thought it would be educational, as well as functional to use the newer Dotnet/Blazor technology to build a server on the Pi. Don't forget you have to enable I2C with raspi-config! button class="btn btn-primary" @onclick="startRead">Start Temp Reading The device data sheet gives the formula for calculating the temperature in degrees C. Some high school physics tells us how to get the F value. Sensors with Pulse Outputs Some sensors ��� 2. In my Pi, that would be http://10.0.2.29:5000. So, we have a console program in Dotnet, with the obligatory Hello Worldl. address for our device is 0x1A, there are also address pins to allow multiple devices, you jumper them high. in the name. Adafruit's Raspberry Pi Lesson 11. To make these 2 environment variables survive a reboot, add them to the bottom of your $HOME/.bashrc file. Since these sensors share the bus, it is difficult to troubleshoot. Our first order of business is to make the server available to other systems on the LAN, the default Url is localhost only. Power supply In Linux, we talk to devices in the /dev folder. I think the MCP9808 is a  little unique in that it requires a write function to tell it which register we want to read. For the basics, fire up VS Code and remote connect to the Pi via SSH:  hit Ctrl-shift-p, then scroll down to "Remote-SSH Connect to host". This is the result of that modification. This will scan for I2C devices and display the addresses of the found ones in a table. In the tempserver folder, add a folder named Services. We need an I2C library to make life easier getting data from the temperature module.
