+#  Dice with 7 segment display
+
+This project can be called as Electronic dice.This will give a random dice number.
+
+##  Components Needed
+
+-  Arduino (UNO R3)
+-  7 Segment Display
+-  Resistor - 1
+-  Jumper wires
+-  Breadboard
+-  PushButton
+
+##  Circuit Diagram
+
+
+1. **Dice with 7-segment display:**   
+    `Power` -> Arduino 5V
+    `GND` -> Arduino `GND`
+    `Vout` -> Arduino `A0`
+2. **7 Segment Display Connection:**
+    - Common -> connected to power along with resistance
+    - a -> Arduino 2
+    - b -> Arduino 3
+    - c -> Arduino 4
+    - d -> Arduino 5
+    - e -> Arduino 6
+    - f -> Arduino 7
+    - g -> Arduino 8
+
+
