Give an algorithm and an Arduino C code for the following: 1. A system that reads the speed of a vehicle in miles per hour and converts it to kilometers per hour. A system that reads a positive integer number and checks if it is odd or even. 2. 3. A system that reads an 8-bit number, N, and checks whether this number matches a 4. A system that reads two 8-bit numbers N1 and N2 and calculates their sum 5. A system that reads an 8-bit input and computes the AND operation between the number, P, stored in the memory (N1+N2), difference (N2-N1).product (N1 input and the mask-0xOF. N2), and division (N2/N1)
