I want to incorporate a pushbutton that when pressed, it will stop the power to the dynamixel motors (actually it will stop the power to the power board that controls the servos).
I am not in a position to use a micrοcontroller, only a relay and a pushbutton.
Right now, the power board is supplied by a power supply, connected to this connector:
But right next to it there are some other connectors, that could maybe be useful in my ideal setup.
If anyone has an idea how this setup can be utilized, i would really appreciate it if he could shed some light.
The Test Points is the route where you can pick a signal (of either TTL or RS485) through this for the test purpose. So this may not be ideal contact to the relay.
If I were you, I would use the right next terminal block ( Left: Ground, Right: VCC) to the barrel jack. And let the relay (You may use Common - Normally Open, In this case, bring the ground to the signal will activate the relay) And bring the signal from the push button to one of “In#” of the relay. Make sure the push button may need to be either Pull Down or Pull Up for eliminating Idle state.
Alternatively, a transistor (Controlling the Gate) might function the similar.
Hope my thought is helpful, and please share your project on this community.
