📘 Included Logic Gates:
- AND Gate
- Symbol: 🔶
- Expression:
x = A • B
orAB
- Truth Table: Only outputs 1 when both A and B are 1
- Sinhala description provided
- OR Gate
- Symbol: 🟠
- Expression:
x = A + B
- Outputs 1 if either A or B is 1
- Sinhala explanation of functionality
- NOT Gate
- Symbol: 🔺
