Capacitor Values

[Pintglass]

Hi
Please could you give me an idea as to what values you used for the capacitors on the 5V inputs for the mp3 module and the audio amp.

Thanks

In all honesty I didn't bother using a capacitor and it seems to work ok. Any low value ceramic capacitor should be fine.

I didnt use any caps either, had no issues, gates worked great for a couple of years now!,

This is wonderful to hear. :)

Sadly my son has moved on from BMX, so my gate is packed away.

Thanks for that.
Can you tell me what pins on the JQ6500 I should be connecting to from the arduino and is it ok to just upload the two wav files to the JQ6500 as I'm not getting any spoken voice.

To upload the wav files you will need to use the MusicDownloader program linked on this page: https://sparks.gogo.co.nz/jq6500/index.html

For connecting the JQ6500, using the diagram on the page linked above:

• RX -> Arduino D10
• TX -> Arduino D9 (with 1000ohm resistor between)
• DAC_L (left channel) -> Amp input
• GND (under TX) -> ground
• VCC -> power input, 5v

Here is my PCB:

Thanks for the help but
Sorry I'm a little confused now, in your text your saying the RX on the JQ6500 goes to pin 10 on the arduino, but on your circuit board you have pin 10 on the arduino connected to TX on the JQ6500
