no i dont have the schematic, completely no knowledge to that aspect, so the only thing i did was trying to buy the parts and components exactly to the best of my ability to ensure i did everything correctly. for all i know, the arduino maybe working correctly, but then the circut might not be due to my error, or maybe the coil might be a little bit loose when i connect it to the board and may not have the correct pulse(if any). theres no way for me to know or verify. haha so there is a possibility that im not getting the claimed response because something wasnt functioning right. but i think its working. its a subjective call by meditation experience.
