Some last tips

These tips are in Q and A form.

Tip 1:

Q: All the LED's are lighting up red on my CPX! What do I do?

A: This means the batteries are dead. Replace them from the battery holder after disconnecting it from the Circuit Playground.

Tip 2 (isn't really a tip, more of a question):

Q: Can I use the Circuit Playground Classic instead of the Express?

A: Yes, you can, but I haven't tested with it.

Tip 3:

Q: Is there any other way to get the speaker input besides the microphone?

A: Yes, you probably could find the pinouts of the speaker connector, solder onto them, and connect them to an analog pin and set it up as an input and then measure the voltage from that. I haven't tried that either, and I'm not going to risk breaking the connector with soldering.

Tip 4:

Q: Can I run it off of the mains power from the speaker instead of batteries?

A: Probably, kind of like Tip 3, by soldering onto the power inputs of the speaker (hopefully 4.5V-5V) and then maybe use that.

So, that's the end of this guide! I hope you like it! This is my first one!
