arduino_lap_timer

based on the original arduino project "Personal Lap Timer" by Duane B. on http://rcarduino.blogspot.com/

This is an Arduino project.

ABOUT:

I'm an IR lap timer, you can use me to count and record lap times... eg: of your RC car model!

You can use 4 hardware normally open push buttons or an old infrared remote control with at least 4 buttons. If your remote control have an extra button, you can use it as "fake-a-lap" feature. If you attach a passive buzzer you can enjoy the "pressure" feature.

HARDWARE:

(mandatory)

• microcontroller (ATMEGA328)
• IR receiver (TSOP31236)
• display 128x64 (SSD1306 or others supported by U8X8 library)

(optional)

• buzzer (any passive buzzer)
• 4 buttons (any N.O. button) or an old infrared remote control with at least 4 buttons

USER INTERFACE:

A very simple interface: ok to enter a mode, cancel to exit a mode and up/down to cycle through any options in a mode.

• OK = enter a submenu / change an option / start a session
• CANCEL = exit a submenu / stop a session
• UP = go to the next element
• DOWN = go to the previous element

MENU:

main (overall summary)
-> CANCEL - memory reset -> OK/CANCEL
-> OK - start new session -> OK -> recording... -> CANCEL/FakeLAP/RealLAP
      - UP - audio -> OK to toggle
      - UP - pressure -> OK to toggle
-> UP - session summary -> OK -> lap details -> UP -> next lap of the recorded session

customization for your own setup

you have to customize getKeys() for:

• FakeLAP you can use a fifth button on your infrared remote control or an extra hardware push button.
• RealLAP use a different device programmed with the "simple_ir_sender" sketch or something similar.
