WITH TSOP1738 CIRCUIT
Fig. 3.5 555 MONOSTABLE CIRCUIT
The sensor used is the TSOP1738. It only senses the signal of frequency 38 kHz. This sensor is used to avoid the reception of signals from other sources. The 38 kHz signal is only used by TSOP1738 so, it can be horizontally mounted.
Monostable vibrator is an 8 pin 555 timer Ic.Pin1 is GND, Pin2 is trigger, Pin3 output, Pin4 reset, Pin5 threshold, Pin6 & 7 is used to design the ON/OFF time and Pin8 is vcc. The output pin of TSOP1738 is connected to trigger pin of monostable circuit whenever TSOP senses the 38 KHz IR signal sensor output p..................[:=> Show Contents <=:]

Procedure –
1) Solder the circuit on the given board.
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.

ombination with a custom integrated circuit that performs the same functions in hardware.
However, a lot of flexibility is lost when a design is hard coded in this way. It is much easier and cheaper to change a few lines of software than to redesign a piece of custom hardware.
History and Future:
Given the definition of embedded systems earlier in this chapter, the first such systems could not possibly have appeared before 1971. That was the year Intel introduced the world’s first microprocessor. This, chip the 4004 was designed for use in a line of business calculators produced..................[:=> Show Contents <=:]

In the above block diagram we are used 89S52 microcontrollers which are a 40 Pin 8-bit, 32 I/O lines. This is the brain of the whole circuit. The robot system consists of RF receiver 433MHZ to receive the commands from the remote. Here the received data
will be in RF signal where it is converted to digital data by RF receiver and input to HT648 decoder which decodes(demux) the digital data and input to microcontroller port1.
