Consists of 8 bit Analog to Digital Converter using successive approximation technique for Analog to Digital conversion. Eight LED’s to display the digital value of the Analog Input.

Uses 8 bit ADC-0809 monolithic C-MOS device with in-built 8 channel multiplexer. Eight LED’s are provided to display the digital value of the input Analog Signal.The complete operation of A/D converter Chip can be understood using this card.

Consists of two independent 8 bit Digital to Analog Converter analog with a stable regulated voltage source using 723 regulator. The current outputs of the DAC are converted to voltages using operational amplifiers.

It provides the user with eight TTL buffered outputs and eight TTL buffered inputs. The logic state of each input and output is indicated by LED’s. It can also simulate Ladder networks.

This interface simulates the control operation of an elevator. The elevator is considered to function within a building having four floors. A key and corresponding LED indicator serves as a request button and request status indicator. The LED’s also indicate the position of the elevator within the shaft. This module is the practical example of use of Microprocessor in industry.

The interface tests 14 pin or 16 pin digital IC’s. Three personality modules are to be inserted in three different sockets for the IC under test. A socket is provided for inserting the IC to be tested.

A four digit display using shift registers can be obtained on corresponding to be put out in serial fashion to the input of the first shift register and clock terminal is pulsed. Has the capability of displaying any segment combination.

Can control Stepper Motor in three parameters such as direction, speed and number of steps. It has got driver transistor for driving all the phases of the motor useful for Robotic and incremental control applications.

A calculator style KB consisting of the Keys 0 to 9, *, +, -, /, C CE and two user definable keys, allowing the user to study a number of techniques used in Key Board interfacing like software debouncing, two key lockout and keyboard encoding and pausing.

A 16x1 Liquid Crystal Display using shift registers can be obtained on corresponding to be put out in serial fashion to the input of the first shift register and clock terminal is pulsed.

The Traffic Light Controller Card has RED, AMBER & GREEN LED’s to demonstrate the use of Microprocessor in contolling the traffic movement under the control of program.

Sensor to measure temperature upto 150oC. alongwith room temperature compensation and amplifier with output of 0-5V corresponding to the temperature.

The VPL-DC card can control the speed of DC motor alongwith its direction under the control of the software programme.

The VPL-ROC has four channel relay & opto coupler to demonstrate how I/O lines can be used to energise the relay and opto coupler to sense the input providing isolation.

The VPL-LED has a matrix of 8 x 8 LED’s and is a module to demonstrate for displaying any character within the matrix.

The VPL-TWSC has two nos. of Thumb Wheel Switches which can be read through I/O lines normally used in industrial controllers. The Study Module Cards can be connected to 8085 kits to perform study on individual IC’s. It has LED’s to display all the important signals like READ, WRITE, CHIP SELECT & DATA. These modules can be connected to Microprocessor using 50 Pin FRC cable and are useful to study peripherals IC’s.
