Hi guys. I have two cats, one is Yoko and the other one is named Djony. Sometimes I have to leave them home for more than a day. That’s why I've made this project. An automatic feeder that could be adjusted for different portions and time intervals. I know you could go and buy such a device but I thought it would be a lot more interesting to build my own. I’ve made the design and 3D printed it. Then we control a servo motor with the Arduino, a real time clock to get the hour of the day, some voltage regulators, an OLED display and some buttons. It’s a simple project but I think it could be quite interesting, so if you want to build this same project, stick till the end of the tutorial. Full tutorial here: https://youtu.be/4sTpbmEInvE
