Fingerprint sending

Overview

Press the fingerprint, the green light will turn on if the recognition is successful, and then press the door open key or door close key to send the data through nRF24. The received data is processed in different ways at the receiving end. The receiving end also shares it. The microcontroller does not do low power. Consumption processing, I switch it on and off through the toggle switch on the left. You can use a 51 microcontroller to wake up from interrupts outside the power-down mode to achieve low power consumption.
