Description

Circuit schematic like in Figure 1 above is Circuit Schematic Circuit Schematic 2 RFID based Attendance System using 8051. Electronicshub site describe that first we’ll see the basic connections with respect to the microcontroller. Here, we’ll need to connect a crystal, a reset circuit and external access.

To use the on-chip oscillator, an 11.0592 MHz quartz crystal is connected to pins 18 (XTAL2) and 19 (XTAL1) of the microcontroller. Two 33pF ceramic capacitors are connected from the crystal to ground.

The reset on the 8051 microcontroller is active high i.e. upon applying a high pulse to RST pin, the microcontroller will reset. A 10KΩ resistor is connected from the RST (Pin 9) of the microcontroller to ground.

A 10µF electrolytic capacitor is connected between the positive supply and RST pin. A push button is connected across the capacitor.
