The external power can be AC or DC, with a voltage between (7V/12V,1A output) at 230V AC

input. The 8051 board produces +5V using an LM7805 voltage regulator, which provides supply

to the peripherals. USB socket meant for power supply only, user can select or control power

either USB or Ext power supply through slide switch SW2.

5.1 - Light Emitting Diodes

Light Emitting Diodes (LEDs) are the most commonly used components, usually for displaying

pin’s digital states.

The 8051 Kit has 8 nos., of Point LEDs, connected with port pins (P0.0 to P0.7), to make port

pins high LED will glow.

5.2 – Digital Inputs

This is another simple interface, of 8-Nos. of slide switch, mainly used to give an input to the

port lines, and for some control applications also.

The 8051 Kit, slide switches (SW8 to SW27) is connected with port pins (P2.0 to P2.7), user

can give logical inputs ‘LOW’.

The 8051 Kit, have 2x16 character LCD. 7 pins are needed to create 4-bit interface; 4 data bits

(P0.4 – P0.7, D4-D7), address bit (RS-P0.0), read/write bit (R/W-P0.1) and control signal (E-P0.2).

The LCD controller is a standard KS0070B or equivalent, which is a very well-known interface for

smaller character based LCDs.

5.10 - Real Time Clock (DS1307)

The Real Time Clock (RTC) is a set of counters for measuring time when system power is on, and

optionally when it is off. It uses little power in Power-down mode. On the 8051, the RTC can be

clocked by a separate 32.768KHz oscillator, or by a programmable prescale divider based on the

5.14 – Traffic Light Controller

Traffic light controller section consists of 12 Nos. point leds are arranged by 4Lanes. Each lane

has Go(Green), Listen(Yellow) and Stop(Red) LED is being placed. Each LED has provided for

current limiting resistor to limit the current flows to the LEDs.

5.15 - RS-232 | Interrupt Communication

RS-232 communication enables point-to-point data transfer. It is commonly used in data

acquisition applications, for the transfer of data between the microcontroller and a PC.

The voltage levels of a microcontroller and PC are not directly compatible with those of RS-232, a

level transition buffer such as MAX232 be used.
