I have fried about 3 boards already, can anyone help me sort out my situation. Is there something Im missing in my connection? TIA [circuit] #include <Servo.h> #include <Arduino.h> #include <EEPROM.h> #include <LiquidCrystal_I2C.h> // Servo for dispensing cigars for the single brand Servo brand…

but it is, I assumed it's easy, turns out there's too much technical terms and skills I still need to get my project working.

[image] Hello, I used this specific thread and image as reference

An image is not enough. Provide some part number for the coin machine and if you seen any wiring diagram anywhere, share the link

[image] bingbongfx: but it is, I assumed it's easy, But as you found out it is not. [image] bingbongfx: there's too much technical terms and skills I still need to get my project working. You can't even seem to finish your physical layout diagram, like the voltages on the top right ha…

[image] How to Control CH-926 Coin Acceptor With Arduino How to Control CH-926 Coin Acceptor With Arduino: In this instructable I am going to show you how to program the cheap CH-926 coin acceptor . I will configure it to recognize 5different Euro coins and connect it to arduino. …

I will take look and see if can figure it out

more of a hobby that led me here. was only DYI'ing ,it isnt my field of expertise, thanks for the help though, will try to watch the video

by the way, will it burn another component from the board if the regulator was burnt? Im planning to buy a regulator for the fried boards and re solder it instead.

[image] bingbongfx: Im planning to buy a regulator for the fried boards and re solder it instead. You know what is the best way to burn an Arduino? It is to connect a higher voltage to it when the Arduino itself is powered down. Say, for instance, having the 12V from the coin acceptor still …

Your wiring matches the video up to the blue wire to pin2 and pull-up resistor but the video very clearly tells you "Use 5v for the Arduino" and the servo motor is not in that project. nor the push button. These modification of the project is likely the cause, but never give12v input to Arduino
