# Arduino
My Arduino Sketches.
If anyone is interested enough to read a blog article about how I did any
of these, please contact me and I'll write one.
## test-128x64ZW
Simple test of driving a 128x64 LCD display using U8Glib. Set up for a ST7920
via SPI, but any of the other U8Glibsupported types would work, of course.
## Distance1
Sinmple read of an ultrasonic distance sensor, giving a time of flight in
microseconds and distance in centimetres over the serial interface.
## MCP23017-first
Drive an I2C connected MCP23017. Set up for 8 LEDs attached to GPA0-7, a button
attached to GPB0 and another LED to GPB1, controlled by the button.
### MCP library
A simple library to drive the MCP23017, which allows for setting pin direction
individually and in bulk, and reading and writing of the pins indivdually and in bulk.
## Keypad1
Simple read of a 4x4 keypad, using the Keypad library, outputting the pressed
keys over the serial link.
## ReadJoysticks
Read 2 analog joysticks and output the raw values over the serial link.
## Stepper1
Drive a 28BYJ-48 stepper motor via its interface board continually one
revolution clockwise, then counter-clockwise. The time for a revolution and
hence the RPM are output on the serial link.
## LCD-first
Very minimal check of a connected LCD display.
## WS1812B
Use the Adafruit NeoPixel library to drive my 8-LCD pixel bar with a rainbow pattern.
Updated to 24 LCDs.
## stepper-driver
## Badge1
First version of the sketch for my proximity badge. This one just displays the
distance from an ultrasonic distance sensor in different colours of the NeoPixel strip.
## Badge2
Second version of the proximity badge, which has the added 4x20 LCD. The LCD is cleared
when there is no one around. Now that I know how to turn the backlight on and off
under program control, I will do that next time.
## Joysticks-128x64
## Joysticks-128x64-Graphic
## Keypad-MC17-4x4
Read a 4x4 keypad connected to a MCP23017 i2c interface and output the pressed
keys to the serial link.
## Keypad-MC17-4x3-128x64
Read a 4x3 keypad connected to a MCP23017 i2c interface and output the pressed
keys to the LCD screen.
## Keypad-MC17-4x4-Multi
Read a 4x4 keypad connected to a MCP23017 i2c interface and output the key press,
release, and hold information to the serial link.
## LCD-Joysticks
## LDR-Reader-128x64
## Stepper-MCP
## Sweep
Sweep a servo from one end to the other, using the Servo library.
## conway-life-128x64
[John Conway's game of life](http://www.conwaylife.com/) implemented on the
128x64 LCD. Updated to use the newly discovered
[Copperhead](http://conwaylife.com/wiki/Copperhead)
spaceship which goes across the screen in a little over 500 generations.
## keypad-MC17-stepper
## keypad-stepper
## meArm
## Oscilloscope1
Simple oscilloscope which outputs to a 128x64 display. Initially set to 1V per
division vertically and 100ms per division horizontally. Updates twice a second.
Tested with the output from a 2 transistor oscillator at about 4Hz.
