Lemonade Automat

I am Science and Technology teacher at middle school in my country. I teach science, electronic and robotic skills to my students in free times after lessons. My students ages are between 12 and 13. Every year we make science fair in spring. Intelligent glass, maze solver robot, lemonate automat, meteorology balloon, auto balanced car, etc. are some project we do in this year.

This project based on Arduino Nano. You can see schematic in picture. 

We use Arduino Nano, MAX7219CNG for 10 Led Bar Graph, Coin Acceptor, Buzzer, 3-6V Mini Water Pump, I2C 16X2 LCD, 3 buttons and 2 distance sensor. After produced pcb we will make box to this machine and we will share instructions on github. We will put this machine at fair area. We will buy sensors to our robotic education class after this machines earn.

We know PCBWay supports students, teacher and makers. We want and wait support me and my students. If you support this project we will produce this machine pcb to you :) Thanks for supporting.
