So here we have our automatic screw feeder with our counter and carousel here to get all of our counted screws in. So this is doing counting for our useless machine parts. So first step we want to do is put in the air from the air compressor and the tool air inlet and then turn the air supply on, turn our power on and start the by-bowl for feeding and then wait a few seconds, prevent it get initialized and then we press the red button and get it going. Now our screw feeder will count batches of 22 and we have 25 of those batches. So we have here is our air coming in through a regulator because we don't want it to be full pressure. It goes down into our dual relay pneumatic system here and this alternates air on the switching mechanism to make the screws get caught here and then it pushes it down the line and through this clear tube which we have beam breaker and infrared beam breaker counting and that goes down into our pill bottles. So what we have controlling this relay system is an Arduino here with some transistors on board to handle that current and it also reads in the sensor input and also has inputs for this button and the only other thing is our vibratory feeder which is a bowl that vibrates and makes these screws go up this line up here all the way up and then get fed into the mechanism that switches and pushes them down into the balls. So here we got our pill bottle carousel. This is what all the screws get fed into and we cut the top section here out of acrylic with our laser cutter. Down here we have our lazy Susan type bearing and then we got our open beam setup and that's using our open beams to mount our stepper and the free Arduino with the commander shield on here and then lastly we have this wired portion that goes to the vibratory bowl feeder and that takes commands from that Arduino on that side to advance the orbital carousel.
