On off relay
WebA relay is an electrically operated switch and like any other switch, it that can be turned on or off, letting the current go through or not. It can be controlled with low voltages, like the 3.3V provided by the ESP32/ESP8266 GPIOs and allows us to control high voltages like 12V, 24V or mains voltage (230V in Europe and 120V in the US).

When power is removed from the relay module, the relay contacts will be in their "de-energized" (aka "Normal") position. When the RPi is powered down, the voltage across C1 will begin to drop as it discharges through the …
WebThis project describes how to build a “soft touch” switch. By “soft touch” we mean that you have to push once to set the device ON and push again to set the device OFF. This kind of switch works by latching a relay to ON state with the push of a button and with another push latch is released. It is working like flip-flop states. WebHá 1 hora · 27 Mins Ago.
