ESP32 is a source of infinite frivolity. My latest project does exactly nothing, except when certain door is opened. Then it logs into Wifi and continues to do nothing. Except now my desktop computer can ping that address and inform me the bloody door is open.
- ed25519FUUU 6y agoWhat’s funny is that it’s still probably cheaper to do it this way than with wireless reed switches, which often cost more but are much simpler??
- fluffything 6y agoMaybe for other people, not for me. My free time is very expensive. An ESP32 costs nothing compared to the cost of my free time, and comes with wifi and bluetooth, which makes many things simpler. Other solutions whose hardware costs less than an ESP32 cost me a lot of time, and end up being infinitely more expensive than the ESP32 approach.
- pvitz 6y agoWhich power source do you use for this project?
- timonoko 6y agoTiny Lithium. A diode drops the voltage from 4.2 to 3.5 . Mechanical switch connects the power when the door is opened.
