Senior Project: Wireless Charging Bluetooth Clock¶
Idea¶
This idea was pretty simple, I wanted to make a clock that has wireless charging functionality. Though I looked on the internet and saw too many products that do exactly the same thing. So I decided to add something extra: Bluetooth speakers. For the longest time I’ve been wanting bluetooth speakers so I can listen to music and do my assignments, and I’ve also wanted a clock so that I don’t have to check my phone constantly. With this project, I can check all the boxes while charging my phone wirelessly.
Speakers¶
First thing I looked for was how to get the bluetooth speakers working. I was that the speakers I was gifted were rated at 3W and 4Ω. I wasn’t exactly sure what those ratings meant so I did some research to figure that out first.
I came accross the following links and videos
Next I had to figure out the bluetooth connection. This required a little more research. Speakers require an amp that has a similar rating to the speaker. The amp is what actually provides the audio to the speaker. Next I would need a bluetooth audio board to connect my phone to the amp. Their are two possible ways to do this and the video below explained everything.
- Get a board that has both bluetooth and amp functionality at the same rating of the speaker
- Get two seperate boards one bluetooth and another as the amp. Then use an aux cable to connect the bluetooth board to the amp.
