Resumen
This document describes the development of a safety and registration system for a bicycle parking area by means of a microcontroller, which allows a correct operation of all the processes involved in the system. The microcontroller PIC 18f4550 was used, this was used to receive the data of the RC522 module used in the system of entry, and with this is made the reading of the RFID cards that are the ones that determine the entry or exit of a user, also the microcontroller makes a display on a 16x2 LCD and also has three indicators to know the state in which the parking lot is (input, busy and output), plus a serial communication RS232 between the microcontroller and a module WI-FI NODEMCU ESP -8266 which was configured as a server to upload data to Google's FIREBASE platform. An Android application was also developed in ANDROID STUDIO for mobile phones with Android operating system with a version superior to 5.1 in which the user registry data is visualized in real time and can be monitored by security staff. The safety system by means of the solenoid is vulnerable and a more compact system should be implemented, in addition to the space used for each bicycle it should also be subjected to more tests in order to have a simpler model and for smaller spaces. The database fulfils the proposed functions, but its interface could think about improving itself.
