Hi! Thank you very much for your explanation, it's quite clear. I read your comments in the "wearable jammer bracelet" and I would like to know if your prototype is still ok ? I understand that when you try with a 25Khz transducer and the cheap Mini power amplifier board, the prototype was not very efficient. Also, I have an Arduino Uno, I wonder if I can use it instead of the arduino pro micro used in the tutorial.

Thanks again!! I would like to make my own alexa-jammer :)

Bye

My prototype is okay, but range is somewhat limited. I could of course use an amplifier with more power, but I'm a bit worried about hearing loss because I can't measure how much decibels the device is outputting.

You can totally replace the Arduino Pro Micro with an Arduino Uno or any other Arduino for that matter.

Ok, thanks I will to try to do that. First, I will try without amplifier (like you did in the picture), because the shipping of the amplifier is very long.

Thanks !

Hello, I have received all my parts and after installing my amplifier I notice that the sound intensity is lower than when I connect to a 1Kohm resistor. I bought a PAM 8403 3W amplifier (without potentiometer). Do you know why ?

Thanks.

No, I don't know. You didn't even tell me what the resistor is connected to.
