Abstract

The causes of traffic congestion are divided into two, one of which is natural factors and the other is human factors. One way to resolve this is by diverting the flow. Usually, the diversion is carried out by the police. The other way to divert the flow is by using a signboard that can change its direction. This board is made using the P5 RGB LED panel and the NodeMCU esp8266 microcontroller. This panel uses the Internet to communicate with the database. The database used is the Firebase that contains the name of the city and the direction to the city. It used the HTML Protocol to send the data from the database to the board. From the tests that have been done, the results obtained shows that NodeMCU esp8266 is not suitable to be used by the PxMatrix Library for large panel configurations. But on a small panel, the test was successfully carried out. The test was carried out by changing all directions of the city. The result of this test is that the direction of the entire city can be changed according to changes in the Firebase.
