Should this code not be digitalRead(10) rather than digitalRead(7) since there is nothing connected to input 7?

Hi, would you be able to help me do this with a different hopper? I have an asahi seiko sh400

[@djpaulbailey]

Hi I’m struggling to get this code to work on my arduino mega 2560, am I doing something stupid?! Could you help if possible please? I’m using an asahi seiko coin hopper. How does your code sense the hopper coin count and how does it determine what coin has been put in?

Hello I really like your video is awesome I have try to replicate your code but I keep getting an error with the LiquidCrystal_I2C.h library I downloaded added to my library Mist of them but keep getting No such file or directory Plz help
