Arduino circuit design and code

For my project i need a fairly simple arduino circuit design alongside the code. whats required here is specifically the circuit design similar to the format of the uploaded picture. note that Arduino Uno is used for the project. The requirement of the circuit is as follows : - Controls the rpm of a DC motor. (voltage supplied by a battery) - measures and records the rpm of the motor to the pc using an encoder. - count the number of cycles or rounds the motor shaft has done. - on/off switch - includes an LED which when detected by a light sensor stops everything. the code should function to run the motor at a specific rpm, count the number of cycles, and halt the operation when the light is detected.
