The last step for the mechanical aspects of the pill dispenser was to measure from the bottom of the large circular acrylic tube and drill holes in which ¼ in plugs were glued in to hold up each layer of the pill dispenser. Holes were also cut for each pill slide to eject and also on the back for wiring and to load more pills into the dispenser, see Appendix C for pictures of the competed pill dispenser from different angles. We used 4 main levels with the level 1 (the top) for round pills, level 2 for oval pills, then we had a trap door for demonstration and the bottom level had the motor mounted to it.
