Building a Robot Arm with .NET 8, Raspberry Pi, Blazor and SignalR - Peter Gallagher

Learn how to build a robot arm using .NET 8, Raspberry Pi, Blazor & SignalR. Control servos, integrate real-time communication, and create cross-platform IoT interfaces.

Key takeaways
  • .NET 8 can run on Raspberry Pi and enables building IoT projects using C# and familiar tools like Visual Studio
  • SignalR enables real-time bi-directional communication between devices and servers/clients, making it ideal for IoT control applications
  • Blazor provides a modern web UI framework for building interactive IoT control interfaces without JavaScript
  • PWM (Pulse Width Modulation) is used to control servos and motors by varying pulse timing
  • The System.Device.GPIO NuGet package provides hardware abstraction for interfacing with GPIO pins and peripherals
  • Remote debugging capabilities allow debugging code directly on the Pi from Visual Studio
  • Multi-platform capabilities enable controlling IoT devices from web, desktop (MAUI), mobile and VR interfaces
  • Device bindings in .NET simplify interfacing with common IoT components like servos, sensors and displays
  • Running .NET on constrained devices requires consideration of timing, resource usage and hardware limitations
  • IoT projects can serve as engaging educational tools for teaching programming and STEM concepts
