First time poster long time reader
. I'm trying to create a circuit that will turn on a relay when the trigger is pushed this will stay on for t seconds. As soon as the relay turns off 555B turns on another relay for t seconds.
I am going from the circuit diagram attached. I have connected the 1st relay to the 3rd pin on 555A however when it is connected lm555B is not triggered.
I assume the relay is drawing all the voltage away from the 2nd pin on LM555B. Does anyone know how i can split the voltage/current so that my relay will switch on and the LM555B will be triggered.
Thanks in advance
