I currently have four actuators and 8 relays I am controlling. I am using a serial window to control them. To control the actuators I have 12 keys including forward, stop, and backward.
Actuator 1 forward - Q key
Actuator 1 stop - W key
Actuator Reverse - E key
I have to hit Q, then enter and it keeps going forward until I hit W, then enter to stop. I would like to set it up where I hold Q to go forward and when I release the Q key the actuator stops (this way I could get better control and use only 8 keys). I was thinking of a serial window that sends a (Q for example) every .01 second that it is held and the actuator would run for that amount of time. Does anyone have any suggestions on how I could do this or examples they know of on the web?
