For doing their activities, blind people need tools. The idea for designing this device is for helping the blind person. This device is a glasses specially for blind person which gives information in the form of voices through an earphone if there is an obstacle in the range of 0-58 cm. The device is using PING ultrasonic sensor, ATMEGA8535 microcontroller, and ISD25120 for recording and saving the voices. After designing and making the device, we tested the device to take the data. We use

The voices depend upon the output of the PING ultrasonic sensors. Keywords: Glasses ISD25120 Microcontrollers Ultrasonic sensor Voice This is an open access article under the CC BY-SAlicense.
