DEVON AND CORNWALL GNU/LINUX USER GROUP

http://www.nikeairmaxfreedom.com nike air max 95


The aims of the Devon and Cornwall GNU / Linux user group are :

  • To help users of all ages / backgrounds find other users of GNU / Linux and Free software
  • To provide a friendly support network where questions of any level can be asked
  • To provide informal support, promotion and advocacy  to local people / business and industry with regard to the implementation and use of GNU / Linux and Free software OR to provide a links to people who can support this on a more formal level.
  • To provide support,  including promotion where possible to events or other activities in the region.
  • To provide access to support materials,  documentation and educational opportunities which help people use and learn about GNU / Linux & Free software.
  • Hopefully demonstrate there is a active and vibrant community and IT industry in the South West of the UK.

We run an active e-mail discussion list.  Please visit our join page for more details and a link to the mailmail sign up form.

We have an mailing list archive which can be viewed here.

We also run a IRC channel on freenode

server irc.freenode.net – Port 6667 channel #dcglug

Please see tutorials menu for help with setting up IRC.

Arduino easy module shield

Arduino easy module shield

Arduino Sensor Shield

Equipment required:

  • Shield
    Arduino R3 uno
    Long nose pliers
    Scissors to open packet

Upon opening the packet,  you get a shield with a foam protective sheet. Fitting the board is easy(ish) partly as you need to align all pins carefully and if need be adjust the to suit the female header on the Arduino Board. Clasp 1 row of pins and move slightly, be careful doing this.

inspection of the board with the Label at the bottom the digital inputs are at the bottom (near to the power in) top row viewing this way you have analogue in then the power in/out sockets.

  • ax refers to analogue pins
    dx refers to digital pins

so on the left hand side

pins for vcc,gnd,sda & scl
below this going down 2x switches (d2,d3)
dht 11 (d4)
below this the reset switch.

Then there are 2 LEDs blue (d13) red (d12)

Potentiometer (a0)

just above this and to the right of the switches
is a tri colour LED (d9-11)

Next to this are 2x 3 blocks pins connected to (d7 & d8) along with vcc and ground pins in. Under this there is  a small buzzer connected to d5 and under that another 3 pin block with vcc,gnd and connected to a3 pin

finally on the far right hand side

serial (4x pins txd,rxd,vcc,gnd)
under that a IR led (d6)
under that light sensor (a1)
and lm35 temperature sensor connected to a2

So in all this is a pretty comprehensive board, the advantage with this is tht you don’t need to worry about wiring, you plug in the code, the components are labeled and tell you where they are connected so no messing around trying to find data-sheets or notes.

Upon connecting a usb lead for power to the Arduino the Blue LED same as the red LED on the Arduino board, which is by now covered up by the shield.

Quick test of the board using the Arduino blink example (modified)

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
 
This example code is in the public domain.
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
int led2 = 12;
// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
pinMode(led2, OUTPUT);   
}
 
// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(led2, LOW); 
  delay(500);               // wait for 1/2 a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(led2, HIGH); 
  delay(500);               // wait for 1/2 a second
}
