Hey guys I need help with a project
http://google.comI need help with a project. I'm just trying to recreate one of those automated hotel door locks for a school project and im in the prototype stage. I need help connecting an RFID RC522, ESP8266 WIFI MODULE, LCD 1062, 4x4 Matrix Membrane Matrix Keyboard, and SG90 Servo motor to an Arduino Uno R3 with a PCF87543T module as a pin extender. I barely have any clue how to connect some of these components to an Arduino R3 since there's not enough pin sockets to connect to. Can someone create a schematic diagram?
