Greetings,
I am currently building a circuit that controls LEDs using a CD4017. I have used two 555 timers, first one to allow the user set the CD4017 to change automatically (astable), and the second one to allow the user to manually change the LEDs by sending a pulse (monostable).
However, I am not sure of the correct way to allow switching between the 555 timers. I am currently using a SPDT connected to the Vcc of both 555 to toggle on or off, but I am pretty sure this is the incorrect way.
Any reccomendations would be appreciated Thanks!
