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.
- .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
