What is it It is a atmega32u4 development watch with distance sensor laser buzzer RGB LED and RTC inside It is pre flashed with a demo program that can display time inside temperature RTC3231 s temperature and distance Push the switch upwards and the watch will detect distance between you and your target If distance is less than 1m buzzer will sound B and RGB will turn RED at the same time The distance sensor can only detect 0 1 2m range Push the switch downwards and the laser will be enabled Push down again and it will turn off the laser You can look at the introduction video I made Why did you make it I just wanted to make a cool watch for Arduin beginners Atmega32u4 could be recognized as a key board for computers That is why a lot of people use it as a Bad USB That is also the same reason I use it on this watch I added a command that can show your computer wifi passwords so when you connect this watch with a computer a window will jump up and shows all the passwords You can change the BadUSB code to do what you want with computer Just for fun Do not do bad things What makes it special Bootloader is Arduin LeonardoBuzzer Digital Pin 12 RGB LED Digital Pin 6 Laser Digital Pin 13 1 3 OLED SH1106 IIC SDA Digital Pin 3 SCL Digital Pin 2 Button Up Digital Pin 10 Button Down Digital Pin 8 Button Select Digital Pin 9 Breakou GPIOs 5V 3V BAT GND GPIO5 SDA SCL TXD RXD AD0 VL53L0 Distance Sensor IIC Extremely Accurate DS3231 IIC 40 70mA power cost work time depe
