Video on how "Bracelet for the blind" works
10/16/2017 at 08:04 • 0 commentsDistance configuration mode: (about 3:50)
Press and hold the "+ -" button for about 3 seconds to start in the distance configuration mode. Press "+" to increase the obstacle recognition distance, or press "-" to decrease the obstacle recognition distance. The minimum distance to identify obstacles is 2 meters and a maximum of 5 meters. A beep is 0.5 meters (example: when you are in distance configuration mode, press "+" or press "-" to hear two beeps, meaning that the maximum obstacle detection distance is: 2 + 0.5 + 0.5 = 3 meters. Press "+" or "-" to hear a beep, meaning the maximum obstacle detection distance is: 2 + 0.5 = 2.5 meters...)

Modification for "Bracelet for the blind"
10/14/2017 at 17:46 • 0 commentsAfter acquiring the opinions of some visually impaired people and experts, I decided to modify the product. Products will have the following features:
- There are 4 ways to use "Bracelet for the blind"
- The product can be combined with a stick. (The combination of "Bracelet for the blind" with the stick will be the most effective solution.)
- The obstacle detection distance can be configured between 2 meters and 5 meters (distance is configured by push button).
- Will only use a vibrating motor on any finger. The vibration of the motor will gradually increase as you approach the obstacle.
- Can be combined with an external power source to increase the use time of equipment to many days.Mr. Binh is blind, he is blind both eyes due to an accident while working. He often walks with a stick in his hand, to meet and talk to people. The stories always make him smile, he is a optimist love life. and he is a very friendly neighbor.

* The mode of operation.
- Battery charging mode.
- Finger vibration mode.
- Sound mode.
- Alarm mode (Acts as an alarm device in the house. If there is a moving object it will emit sound. Alarm mode is started by pressing hold two " + - " nodes in 3 seconds).
+ The device automatically turns off the power when the voltage on the battery is less than 3.6 volts.
+ Two buttons " + , - " Used to set, increase or decrease the volume of Buzzer or vibrating motors. (Save settings to EEPROM).
+ Voltage boost module (3.7V --> 7V). Used to power the Arduino pro mini.
Bracelet for the blind
The solution is leveraging from the available stuff, affordable.
