Testing out this DFRobot gesture recognition module...

Compared to the gravity voice recognition module, this one appears simpler.
But, same warnings about interface apply (Beware 5V!)

This one uses a lot less power, only ~100mA at 3.3V as recall.
Think this one will be useful pointed backwards from robot, so can control with hand gestures.
Or, maybe just have robot stop of person not detected...

Shows up as expected on I2C scanner.
The github archive for this one looks similar to voice, so hopefully can get it going soon.

But, just like voice, can interact without MCU. It's fun. Just can't control anything without MCU connected...
This one is also giving me trouble with I2C interface....
Just figured out that a delay is needed in the read I2C function to get good data...
Ignoring the CRC from the device on read here, but think need to add that, just to be 100%
This code reads the PID from the device and displays it... Should be $272
There is also an issue with I2C not working sometimes when code is restarted...
Power cycle fixes it, but hope there's another way...
Doesn't make any sense but seems that if serial terminal (PST) is disable for a minute or so, then the I2C interface fails.
That is really weird.. Have to think how this can be...
Remember now that closing terminal can reset mcu…
Have similar code in eeprom that fooled me into thinking was not reset…
