Timerino is a programmable darkroom enlarger timer built upon an Arduino microcontroller. Currently it has linear and geometric (f/stop) exposure functions.
Currently supports 2 models which differs only in the display:
- DL-series has a 7-Segment 4-number LCD display and a 10-led bar
- CMG-series has a 16x2 matrix LCD display
If you have some problems using Timerino please file an issue here.
If you can fix an open issue, fork & make a pull request.
Your grocery list to build Timerino is:
- Arduino UNO/Duemilanove
- a power supply transformer 12V 1A
- a case
- 4x4 keypad
- female 1/4" jack and pedal (optional)
- 220V relay
- 2 toggle switch
- a 10K resistor
- a 330 resistor
Model DL002A specific components:
- 7-Segment 4 number serial LCD display
- Grove LED Bar
Model CMG001A specific components
- 16x2 matrix LCD display
- 1 or 2 potentiometers
Follow the appropriate schema for your chosen model (Fritzing and JPEGs included) to wire up the circuit.
To build this sketch you need, besides core libraries, the Keypad.h library: http://playground.arduino.cc/code/Keypad
