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