Arduino odometer

This is simple project for write own odometer for enduro motorcycle with hall sensor and ssd1306 i2c display screen (128x64)

Screens are switching by long hold of center button (500ms+) or click to "menu" button

Screens

"Main" screcen

• current distance. Can be dropped by center button click
• local distance. Can be corrected by left/right buttons

"One km" screen

Define how much ticks in one kilometer (for set correct length of wheel). Special mode for riders. Need to set zero value before start conditional kilometer stay this screen and ride. When kilometer ends, click to center button to define correct value and switch to next screen.

for set new value, use center button. left/rigth - for correction. center long hold - next screen

"Diam, mm" screen

Define diameter of wheel in millimeters.

• top number - is new value
• bottom number - is old value

for set new value, use center button. left/rigth - for correction. center long hold - next screen

"Len, mm" screen

Define length of wheel in millimeters.

• top number - is new value
• bottom number - is old value

for set new value, use center button. left/rigth - for correction. center long hold - next screen

"Info" screen

Shows info about Engine, Oil, Gear counter.

• left/right - for switch between of counter
• center - for drop current counter

Equipment:

• Arduino (i'm using nano, atmega328p)
• Hall sensor (ky003)
• I2C display based on ssd1306 chip (0.91` 128x64 I2C OLED)
• Fram FM24CL16
• wires
• 4 buttons
• 4 resistor (2.2kOm)
• and any type of power for arduino only
