1. Interface LCD with LPC2148 ARM7 controller and display your seat number on LCD.

2. Interface UART with LPC2148 ARM7 controller and transmit your seat number towards the PC.

3. Convert Analog Voltage to Digital using inbuilt ADC of LPC2148 controller and display converted data on LEDs.

4. Interface 7-Segment Display with LPC1768 Cortex controller and display 0 to 9 on 7-Segment Controller.

5. Interface I2C based EEPROM using inbuilt I2C peripheral and write-read data A to Z characters in EEPROM and display same on hyperterminal of PC.

6. Interface 7-Segment Display with LPC1768 Cortex controller and display 0 to 9 on 7-Segment Controller.

7. Convert Analog Voltage to Digital using inbuilt ADC of LPC2148 controller and display converted data on LEDs.

8. Plot the V-I Characteristic of SCR using SCR trainer kit and measure the IH and IL current of SCR.

9. Draw the V-I Characteristic of MOSFET/IGBT and plot output characteristic and transfer characteristic of MOSFET/IGBT.

10. Verify the range of firing angle of SCR using UJT triggering circuit and observe the waveform across the load and SCR.

11. Observe the load voltage waveform across the R and RL load, for Semi converter using PSIM software measure the firing angle and average output voltage across the load.

12. Speed Control of DC shunt Motor (separately excited) by Armature Voltage Control.

13. Study of DC step down chopper. Observe the duty cycle for 10, 20, 40, 50, 60% and draw it on graph paper. What is the effect of duty cycle on output voltage?

14. Single Phase Full bridge Inverter using MOSFET/IGBT for R Load. Observe the output Voltage waveform across Load.

15. Observe the load voltage waveform across the R and RL load, for Full Converter using PSIM software measure the firing angle and average output voltage across the load.
