I have created a robotic gripper. However, I need help in the control circuit:
There are two buttons, the upper and lower one (connected to the timer):
the upper one is two states timer either up or down (will be replaced with an active low pin in PCB design).
the lower one is a push button that must be pushed and let back to its initial position to give a pulse to the monostable timer to make the servo rotate long enough to just close the gripper (calculate with the RC circuit).
My problem: I want to replace the down button with some component so as to give a quick pulse when the upper button change state.
For example, the button was 0 and went 1 -> Component -> a small pulse to drive the timer (not a pulse that will last until the state changes):
- Green: is button state
- Red: trigger pulse needed.
