Distance Measuring Watch
In this project, I have compressed and mounted the Arduino distance measuring system on to a watch. The project is cool, simple as well as useful. The distance measuring system is based on simple physics of distance, velocity, and time.
Supplies
You need the following supplies:-
- Arduino Nano (or Pro Mini)
- I2c OLED 128 X 64
- Ultrasonic Sensor ( HC-SR04)
- A 9V battery and Clip
- An old Wrist Watch
- Mini Breadboard (170 pts)
- Jumpers
- Double-sided Tape
Assembling and Schematics
Assemble the components as follows
OLED - Arduino
GND - GND
VCC - 5V
SDA - A4
SCL - A5
HC-SR04 - Arduino
GND - GND
VCC - 5V
TRIG - D12
ECHO - D11
9V BATTERY - Arduino
+ve - VIN
-ve - GND
Uploading the Code
Upload the project code onto your Arduino board. Check your correct port and board type. Download the required Adafruit SSD1306 and Adafruit GFX libraries.

Testing the Circuit
Connect the battery to the circuit and test if it works properly.
(Final Step) Mounting on Watch
Stick the breadboard to the battery using double-sided tape. Now stick the other part of the battery to the watch using another double-sided tape.
