Tell us about yourself!
You first use a pnp resistor and a pullup resistor. This means that your status of the pin has to be always high. Unless you want to Toggle then you Digitalwrite(2,LOW);And your pnp resistor Toggles the nnp transistor which Toggles the Relay.I still would suggest optocoplers or solid state relays.
hey if you use relays a lot with your microcontrollers you should look into optocouplers.becouse then you succefully isolate the circuit of your microcontroller.you will see that comercial relayboards olmost always use an optocoupler.sorry for my english. just trying to help :)took me a while to learn about them.

thanks for this.i like the great detail it helped me a lot
this is simply amazing great work mate.

"The Bone Collector" Stacked Skull Cake
thats why we use optocouplers.you can add a pnp transistor if you want.just wanne remove frustration :)
that relaydriver wont work with the esp2866-01the esp wont boot correctly. cause it pulls the GPIO2 low.
