So,
Friend got button and ISD1820 module.
We have problem trying to connect it.
I know there are simpler ways to do it but they choose this type for project.
Button is classic two wires
Can anyone give me some scheme? They told me its not working if they connect to pin on module
This link says "REC" pin is waiting for an external HIGH for recording. Wire a button and a pull-down resistor from this pin to VCC. When the button is NOT pressed, it is held low. When the button is pressed, it shorts to Vcc (HIGH). You need to hold the button for the entire "record" time.
