| 説明 | Okay, this is the first circuit of any kind I've ever assembled in my life. And it works. It's a simple circuit of three LEDs connected to the GPIO of the Raspberry Pi, controlled by a 20 line Python script that makes them blink on and off.Baby steps. Eventually I'll be able to use these techniques to get the Pi to run remote- and autonomously-controlled vehicles, robots, etc.The Pi (tallac) is mounted on standoffs epoxied into a chunk of walnut that should keep it out of harm's way (ie, static electricity) while still allowing easy access to the GPIO pins and camera interface.You can see two short lengths of uninsulated 22 gauge solid wire on the bench just above the Pi. I wasn't really sure how the breadboard worked, since I'd never used one before, so I employed these wires with a multimeter as a continuity tester to see how the rows and columns of the holes were connected. |
