Re: Deep sleep rtc

Hello again, I tried to use RTC during sleeP and what it does is that it starts be getting the computer time and after a sleep-wake up cycle it starts counting time from the time esp32 was flashed. On setup I have this piece of code if (!powered) { Serial.println("initialized the clock!"); rtc.begin...

Re: Trying to figure out if esp vroom 32 fits my needs.

Thank you for your answers! Another question is this: I need for my project a vibration motor. The vibration motor says that it uses 78mA to operate in its fullest. The esp32 says that on the 3V pins it can output 50mA. Is that the case, or am I reading something wrong? What could I do to circumvent...
