For displaying images used in digital cameras. jris used in instruments panel where all the lab instruments uses LCD screens for display. The LCDs are commonly used in all the digital wrist watches for displaying time. Pin Configurations The pins for data, backlight and contrast adjustment is explained in Table 3.7.

We are also displaying the readings in the LCD display ti is near the Joad so that it is easy for the user to know the readings when he is near the load. Also we check whether the value measured is correctly updated to the ebsite for monitoring and control. We have selected LCD display specifically of its low cost and also satisfies our requirement in that cost. | 32.6 Loads In this project only one load is used and the load must be single phase load. In this project we use Bulb because to see the variations in the load over clearly because - we can see its brightness being varied more clearly. More over we can see the load being controlled from distant places. » Bulb Here we are using a simple incandescent lamp which is of 230V, 100W. This means the actual power consumed and the apparent power are equal.Here the lamp brightness is dimmed and adjusted by using the dimmer module. 30
