ULTRASONIC RADAR PROJECT FOR THE VISUALLY IMPAIRED
or
THIRD EYE FOR BLIND
on/off switch to control the power of the device
slide switch to change the modes between vibration and sound.
vibration motor which vibrates continuously when the distance between 0 and 40 cm, vibrates for one second and break for one second when the distance between 40 and 80 cm, vibrates for 0.1 second and break for 1.5 seconds when the distance between 80 and 120 cm.
buzzer which sounds continuously when the distance between 0 and 40 cm, sounds for one second and break for one second when the distance between 40 and 80 cm, sounds for 0.1 second and break for 1.5 seconds when the distance between 80 and 120 cm.
ultrasonic sensor to detect the distances between the user and objects through the emitters and send signals to outputs.
Advantages of the project:
this ultrasonic radar is more comfortable to wear and carry than other visually impaired assist systems.
unlike other other products produced for visually impaired it can be worn on the wrist like a wrist watch to allow easy movement so when the person using this product doesn't have to leave or remove the product when he wants to deal with something else.
small.
low production cost.
low production time.
work with low consumption.
can work outdoor and indoor.
if you have a problem with the sound you can be able to change the mode to the vibration mode, to make it silent by a switch.
