Somewhat related to other thread .. but different.
We have a Catapult supported by a ratchet (axle) and potentio-meter. We use potentiometer to get the catapult to certain position to load balls. At this instance the ratchet takes it over and holds the catapult. Once balls are loaded, I use another button to push catapult further when it encounters the chipped teeth and fires off.
The problem is that when I add more rubberbands (tension), the axle (ratchet) chipped away the sprocket teeth edges.
Question : If the sprocket breaks in the competition, looking for options without rachet.
With the above method, we can bring the catapult to desired position to load balls, by holding a button - say btn7L. Once balls are loaded, how do I use another button to push it a little bit further so that it fires off (chipped teeth) ? because if I release btn7L, the rubber bands will pull it upwards. How do I transfer the power to another button while still holding the position.
I tried simultaneously holding another button (btn7L and btn8R) that was supposed to give power to motor, but it didn't work as it should, and the potentiometer held the position.
Thanks in advance.
