5V (on my 5V Nano at least). The voltage divider reduces the 5V to 3.3v and stops the world from being destroyed (or at least the RX pin on the HM-10). 5V Arduinos see 3.3v as HIGH so we can connect the HM-10 TX pin directly to the Arduino RX pin without destroying every...
5V Vcc: Connects the Arduino’s 5V pin Signal: Carries the trigger signal from the Arduino that activates the relay Inside the relay is a 120-240V switch that’s connected to an electromagnet. When the relay receives a HIGH signal at the signal pin, the electromagnet becomes charged and mov...
