The aim of the project is to make the life simpler for the blind people. here used electronic safety guard system that alerts them of any obstacle or object in their path. The system comprises transmitter and receiver section. -Transmitter section -Receiver section uses an embedded system
TRANSMITTER SECTION:
Components used in the transmitter section are TIMER IC 555 CURRENT AMPLIFIER IR DIODES The Timer IC 555 act as astable multivibrator . The transmitter built around the Timer IC 555 which is designed to operate at a frequency of 38 KHZ. This signal is amplified by a current amplifier and transmitted through IR diodes
