Automatic Shot Dispenser v2 | PCB Battery-Powered

Step-by-step guide to building a fully automatic drink dispenser – now in an improved version with a custom PCB and rechargeable battery power (2x 18650 cells)!Boost MeBoost it if you enjoy the files! In this project, I’ll show you how to build an automatic drink dispenser completely from scratch. I started with an existing design and made several important modifications:Added a dedicated PCB for better reliability and easier assembly.Switched to a battery-powered system using two 18650 lithium cells for portability and convenience.Improved component layout and functionality.If you're curious about the original design I started from, you can find it here: OrginalProject🎥 Watch the full build video here: [VideoLink] If you enjoy this project, leave a like and subscribe to support more DIY builds! 🧰 Part List:Drink pump with tubing (or compatible copper tube)Arduino NanoPCB (custom for this version)IRLZ44N MOSFET (important: logic-level gate for 5V control)330Ω resistor2x 10kΩ resi
