hey guys i am new here and have done some minor things with circuits like
leds and small project but i recently created a pneumatic air cannon operated by a sprinkler valve. I have already created a simple 18v circuit( two 9v batteries) and a momentary switch to open the valve; however, I was looking for some help with creating something a little more fancy. Thinking about using a resistor and capacitor( i believe) to set a time interval of when the button can be pushed to fire the cannon. I wanted a master power switch with indicator led. Then after 7 seconds or so power would be ready to pass through the momentary switch ( another indicator led) and to the valve. Simply to prevent the cannon which is CO2 fed to fire before the tank has reached a present psi or on accident injuring someone. then after each fire the current to the momentary would be delayed for 7 seconds( approx).
I have tried to figure this out on my own but i figured i would ask the experts.
opinions gladly taken
