Make Oscilloscope from Bluetooth Headset

$2 For 2 layers 5 PCBs & $5 for 4 layers PCBs: https://jlcpcb.com Use promotion code "JLCATH" to get extra $2 Today's project, I will create an oscilloscope from a cheap bluetooth headset. You will have a bluetooth headset, A smartphone with oscilloscope software. Need 2 resistors 100K or 200K and 1K. It forms a voltage divider. 3.3V zener diode to protect bluetooth headset. The measured frequency is dependent on the quality of the headphones. However, if the frequency is below 10Khz, it works quite well. I'm not sure the software will work with all phones. If it doesn't work, try another software, find the oscilloscope on google play. If you like my video, give me a cup coffee. Thank you very much.
