This interface allows the user to study the interface of a single stepper motor, through port lines and is compatible with our Microprocessor / Microcontroller Trainer kits

This interface provides buffered 12 TTL Outputs and 12 TTL Inputs. Logic state is indicated by LEDs

The 12 inputs are connected to DIP switches and 12 outputs are connected to LED’s and also terminated in pads. The status of inputs are also indicated through LED’s and the inputs are also terminated in pads

A number of experiments like combination controller (AND, OR, XOR and NOT operations), sequential controller, programmable counter, multiplexer etc. can be conducted using this interface
The interface operates off 5V DC and is housed in our standard plastic box

This interface allows the user to study 8 bit DAC (0800) for wave form generation. It has two DACs

8 BIT SUCCESSIVE APPROXIMATION ADC INTERFACE

This is based on ADC0809, which is an 8 bit 8 channel ADC with input multiplexer. The conversion time is 100 microseconds. Input voltage range is 0 to 5V

This provides the user with 20 keys and a 4 digit display mounted on a single board

This provides an example as how the traffic signals are controlled using a processor. The signals are indicated by means of Red, Green and Amber LED’s

LCD INTERFACE

This interface is a 16 x 1 alphanumeric single line LCD display module interface

PRINTER INTERFACE

24 Column Printer Interface

This interface is designed to simulate an elevator. The interface is an example of a four storey building with Green LED indicating that the elevator is in a particular floor and RED indicating request

MULTIPLEXED SEVEN SEGMENT DISPLY

This interface is designed to illustrate the use of multiplexing technique in display interface. It consists of 6 numbers of seven segment Displays. The Seven segments of all the displays are shorted (i.e. ‘a‘ to ‘a‘, ‘b‘ to ‘b‘ and so on) and are driven from a BCD to seven segment latch Decoder/Driver. The individual Common cathodes of the displays are connected to the outputs of a decoder / current sink IC

MATRIX KEYBOARD – 3 X 8

This keyboard interface consists of 24 nos. of computer grade keys, organised as 3 rows by 8 columns, and is designed to interface to the PPI (8255) in our trainers and PCI add-on card
The keyboard is scanned using port lines PC0, PC1 & PC2 and the return lines are connected to port lines PA0 to PA7.
A number of experiments connected with interfacing keyboards can be conducted. The interface is housed in our standard plastic box

This interface allows the user to study the interface of an 8 bit DAC (D800). It provides Unipolar and Bipolar outputs

TEMPERATURE MEASURMENT INTERFACE

This interface consists of a Probe mounted AD590 Temperature Sensor, conditioning Electronics and an 8 bit ADC, AD0809

This allows a user to study the interface of a speaker to generate tones.

The interface consists of single line 16 character LCD display and a 4X4 hex keypad.

The interface consists of 6 numbers seven segment display and a 4X4 hex keypad. The displays are multiplexed.

TEMPERATURE CONTROLLER INTERFACE

This interface is used to study the temperature control mechanism using a Microprocessor / Controller. The setup consists of a sensor (AD590), a source of heat energy (water bath) and a control circuit (interfaced to a kit) to maintain the temperature of the water bath at a specified value. Temperature can be controlled in the range of ambient to 95 degree centigrade

This interface is designed to conduct Real time clock, LCD and keypad related experiments

DC MOTOR CONTROL INTERFACE

This interface consists of the Interface card and DC motor mounted in a single housing. The unit operates off 230V AC, 50 Hz and allows the user to study the interface of a DC motor, to vary its speed through port lines and is compatible with our Microprocessor / Microcontroller Trainer kits. DC MOTOR – 12V DC, 6 Watts
