It is quite spooky when your arduino starts acting all paranormal after midnight.
Why would i turn on the red LED when i reach for the knife ?
It was after i was halfway dismanteling a test setup with a photocell when i discoverd this behaviour by accident.
There will be a perfectly scientific explenation to all of this.
But still :)
int h5=0;
void setup() // run once, when the sketch starts
{
pinMode(11, OUTPUT); // sets the digital pin as output
Serial.begin(9600);
}
void loop() // run over and over again
{
h5 = analogRead(0); // read the value from the sensor
if (h5>100)
{
digitalWrite(11,HIGH);
}
else
{
digitalWrite(11,LOW);
}
// analogWrite(11,h5);
// Serial.print(h5);
// delay(500);
}
What the Character Set of the Arduino's TFT is?
It's CP437.

¿Cuál es el conjunto de caracteres del TFT?
Es CP437.
This lovely little shield is the best way to add a small, colorful and bright display to any project. We took our popular 1.8" TFT breakout board and remixed it into an Arduino shield complete with microSD card slot and a 5-way joystick navigation switch (with a nice plastic knob)! Since the display uses only 4 pins to communicate and has its own pixel-addressable frame buffer, it can be used easily to add a display & interface without exhausting the memory or pins.
The 1.8" display has 128x160 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there's no worries that your code will not work from one to the other.
The shield has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so its safe to use with 5V Arduinos. We also had some space left over so we placed a microSD card holder (so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card) and a 5-way navigation switch (left, right, up, down, select).

I've been working on this on-and-off over a few months:

And now I'm using it in a performance in Canberra!
There is an Arduino in there some where

Holding two red, blinking LEDs as eyes to show the speed and direction of the attached DC motor. The Motor is conceiled in a LEGO enclosure and attached to a LEGO wheel.
For my records, how to wire up the DS18B20 1 wire digital thermomenter (http://www.maxim-ic.com/quick_view2.cfm?qv_pk=2812) but using the two wire functionality here.
I was very excited to get the barometer before the hurricane and I scrambled to assemble something to start logging.
Here you can see both the BMP085 and the DHT22 connected to a home made bread board arduino. Not visible is the linux box which was recording the measurements once every 15 minutes.
使用新的MacBook Pro,Leopard 10.5.2系统，上传程序给Arduino时一直出现B处的提示：“dev/tty.usbserial-A4001bKo” already in use。
此时打开“系统预置”－“网络”，发现在Bluetooth，AirPort和以太网列表下多出了一个“FTR232 UART－USB”选项（有时显示为“USB-Serial”，如A处所示），难道这就是被占用的端口吗？手动删除此选项后问题依旧。天呐～～
