+Answer to questions
+
+Q1. 1 second
+Q2. XOR
+Q3. D3
+
+Q4. This project is one possible solution
+
+The key line is this
+
+unsigned int binaryInput = SW1 + (SW2 << 1);
+
+where SW1 and SW2 are the switches for the least and most significant bits respectively. 
+
+Note the use of << to multiply by 2. A left shift is a cheap operation in computing terms (does not require many CPU cycles).
