presentation on Ir sensors used as a speed senso
Write a presentation on Ir sensors used as a speed sensor and Interface LM393 or HC-020K LM393 as a speed sensor used with the arduino uno. Compare and contrast the two and its accuracy versus modern ways of sensing a vehicle speed. Which is better than the other and would be more accurate to use within an arduino project to display its use and capabilities. Provide detailed information, pictures and provide other possible sensors that can be used as speed sensors that will be cheap and accurate for future use.
