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

.NET 8 now supports IoT development on Raspberry Pi (Pi 4 and earlier) with libraries for GPIO, PWM, and device bindings

SignalR enables real-time communication between web interfaces and IoT devices, allowing remote control of hardware

Blazor provides a JavaScript-free way to create web interfaces for IoT projects, with built-in SignalR integration

Unity can be used with .NET for creating VR/AR applications that interact with physical IoT devices

Basic GPIO components like LEDs and buttons require proper circuit design with resistors and pull-up/pull-down configurations

Servo motors can be controlled using PWM (Pulse Width Modulation), with .NET libraries abstracting the low-level timing details

Physical computing and IoT projects are effective for teaching programming concepts to students and newcomers

Cross-platform development is possible with .NET 8, allowing the same code to run on web, desktop, mobile and IoT devices

The IoT.Device.Bindings NuGet package provides ready-made drivers for many common IoT components and sensors

Development workflow can be improved by using local debugging over SSH rather than deploying directly to the Pi
