Assisting device for visually impaired person. Designing and assembled the hardware Modules

      Аннотация: This report present the designing of assiting device for visually impaired person using microcontroller.It is used to help the blind person travel independently from one station to another bus station. The objective is to develop a assisting device for blind person using RFID and Bluetooth technology. It is designed using an 8-bitmicrocontroller (Arduino MEGA2560) with on-chip ADC, DAC and UART as a core element of the system. It has three keys, buzzer and LCD (16x2) for setting the destination station via blind. As per the selected station, travelling amount will be deducted and blind will acknowledge the destination station via buzzer.
