+## Description
+
+Shot Maker is an automated system that prepares drink shots based on user input. The user selects a drink type from a display interface. Based on this selection, the system calculates the required quantity for each ingredient.
+
+Liquids are dispensed into a glass using pumps or valves. A weight sensor continuously measures the amount poured, and the system stops dispensing when the target weight is reached. For multi-ingredient drinks, each component is added proportionally.
+
+## Motivation
+
+The project aims to automate drink preparation while ensuring precision and repeatability. It explores embedded control systems applied to real-world tasks.
+
+## Architecture
+
+- **Input Layer**: touchscreen interface for selecting drink type  
+- **Processing Layer**: computes target weight and ingredient ratios  
+- **Actuation Layer**: controls pumps or valves  
+- **Measurement Layer**: load cell monitors real-time weight  
+- **Output Layer**: final drink in the glass  
+
+### Flow Summary:
+- User selects drink  
+- System computes ingredient weights  
+- Pumps dispense liquids  
+- Load cell measures continuously  
+- System stops at target weight
