Hey, I'm Linus, I'm currently working on a professional DIY Vending machine with 40 product trays and a change system. I'm using three PCA9685 LED Driver to control 40 360 degrees servo motor and 5 SG90 servos for the change system. I'm using a 4x4 Matrix Keypad as the input, a 16x2 I2C LCD for the interface and a standard CPU Coin Acceptor as the coin detection. I want to use the Arduino Mega as the brain of the organization to control everything. I'm probably also going to add some LED strips or other things. As you can see I'm not nearly done with the project and there will change some things around here and there. The only problem I have is that I'm not good at programming the Arduino. If you want to help me build this project, or want to know more about it just write me a message over EasyEDA. If you are good at programming an Arduino and want to help me, just write me a message as well. (I'm working on the PCB at the moment) Thanks, Linus
