挑戰者專案 - 藍牙喇叭

Putting it together was a fun little soldering project—the Bluetooth module paired instantly with my phone. The button and relay setup for switching modes works exactly as described. Sounds great for a DIY build.

Putting the Bluetooth module together with the relay was surprisingly straightforward, and the button integration lets me switch modes without touching my phone. The whole setup feels solid once everything is wired in, and my playlists sound great through it.

Wired the relay to toggle between the speaker and a silent mode, and the button integration honestly works better than I expected for a DIY kit. It's not plug-and-play, so bring a steady hand, but once it clicked, streaming from my phone was seamless.
