OUTPUT DEVICES

For this assignment the goal is to add an output device to a microcontroller board that I have designed and program it to do something. I have tried to do a Fabduino, but I have had a lot of problems because at the end, it didn´t work. I am trying again to do another one. Finally I did all in Arduino. I connected the ultrasonic sensor SR4, LCD and Arduino. I made a code in Arduino with Yallico that allows to detect if one object is passing throw the sensor and if the person goes to one direction or another. It is good for my final project to detect how many people is going inside or outside of the pneumatic estructure that I am proposing.
