from the anode will travel through the wire as a current to the cathode where they are needed to complete the electron deficient reaction there.
Dry lead acid battery of 12V/1.3A is used as source of power for the whole robot unit. For digital circuitry 5 volts needed is derived from 12v battery using regulator IC7805.
4.12 REGULATOR:
A discrete voltage regulator fabricated on a single chip, it is called monolithic voltage regulator. These regulators have:
i. High performance (ideal 100% regulation)
ii. Low cost.
iii. Reduced size.
iv. Easier to use.
Usually monolithic voltage regulato..................[:=> Show Contents <=:]

2) Connect respective pins of each gate to the corresponding pins of other gate.
3) Connect the outputs ‘sum’ and ‘carry’ to two LEDs.
4) Apply different combinations of inputs as per truth table and note down the corresponding change in the outputs of the circuit.
5) Tabulate the readings.
Brief theory – half adder is logic circuit, which can add two binary digits at a time. In half adder, there are two inputs A & B with two outputs SUM and CARRY. The SUM is the output of Ex-OR gate and CARRY is the output of AND gate.

omparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA.
Both the inputs and the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the output can drive loads referred to ground, the positiv..................[:=> Show Contents <=:]

Port 3 also serves the functions of various special features of the AT89S52, as shown in the following table.
Table 4.2
RST
Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device. This pin drives high for 98 oscillator periods after the Watchdog times out. The DISRTO bit in SFR AUXR (address 8EH) can be used to disable this feature. In the default state of bit DISRTO, the RESET HIGH out feature is enabled.
ALE/PROG
Address Latch Enable (ALE) is an output pulse for latching the low byte of the address during accesses to external memory. Thi..................[:=> Show Contents <=:]
