I'm trying to build the switching electronics for formula student paddle shift system, and we have decided to control the actuator using limit switches.
So the idea is;
1. Press the change up/down paddle, turns the actuator on
2. Actuator moves, until it gets to the end of its travel, about 25mm in
3. Actuator hits a end of travel limit switch
4. Limit switch turns off the power supply to the actuator, regardless of whether the up/down shift paddles are pressed.
5. Actuator remains off until the next rising edge from the paddles
I am struggling to figure out a system that can achieve that, I have tried switching using D flip flop, with the paddles connected to the clock, and reset to the limit switch button, with no success. Does anyone have an idea on how to do this? It seems like such a simple thing to do but i just can't seem to get it to work!!
