msp430-launchpad

A sunlight ray interpreting is a device which is having an application in finding a suitable place for installing the solar plates. It is governed with the help of a microcontroller msp430 and Light Dependent Resistor (LDR)sensors, a Light Dependent sensor which will keep watch the frequency of sunlight falling on it.

Description

Light Dependent Resistor (LDR)

The Light dependent resistor is connected to Port 1, +5V (configured to act as input channel for the ADC). The SAR ADC on MSP430 converts the analog values supplied by the LDR to digital values. The LDR is connected in a voltage divider circuit with a 10K Ohm's resistor
