What? How? Explain please. I've been interested in this for a while, and I know how cheap the ATTINY85 is but I just started experimenting with the Arduino, and just got a relay to switch on/off. Still learning how to get the ArduoCAM to work, and how I can transmit images over WiFi. My point is, can you link to a tutorial? I'm a newb, but I'm a fairly competent full-stack developer.
