Related Hardware DOIT Esp32 DevKit v1

I'll be programming the ESP32 Doit DevKit v1 with a firmware which turns it into an EZ-B for EZ-Builder to connect and control. We'll hook up a servo and demonstrate how to move it. Maybe move it with speech recognition. Show the ADC Graph on how the ADC works, do the same for Digital IO.

Very cool, I ordered a bunch of ESP32-CAM last week from China $10 CAD each. Looking forward to receiving them and trying with EZB

edit: Tried this on an ESP32 today worked like a charm :-) great work DJ

Is the camera/microphone working on a esp32-cam?

I looked into it and there’s only enough processing power for 2/4 frames per second. Which you can see on YouTube examples. It’s good for taking a photo every few seconds for surveillance, but the camera sensor and processor can’t be useful with robotics. 

for a WiFi affordable camera solution with audio and robot I/o, take a look at the ezrobot iotiny, which i am a fan of for small projects. 

otherwise, most robots should have an onboard computer anyway (lattepanda is my selection) and usb cameras work best

Light levels on OV2640 in CIF 400*296 are pretty bad in 800*600 is ok but can't get decent frame rate and seems to overheats over 10fps.
