above that pic, we can identifiy which one the coloums and rows (a,b,d,c,e,f,g,dotpoint) portD (atmega8) most scheme connected as rows meanwhile portB (in arduino call D8 .. D13) connected as coloums. need more 2 wire for coloums try use portC and the question is how the code ?

The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). Additionally, another pin must be used to select the SD card. This can be the hardware SS pin - pin 10 (on most Arduino boards) or pin 53 (on the Mega) - or another pin specified in the call to SD.begin(). Note that even if you don't use the hardware SS pin, it must be left as an output or the SD library won't work. just visit : http://www.hobbytronics.co.uk/arduino/arduino-shields/arduino-microsd-shield Documents: Schematic Eagle Files SD Library (FAT16 and FAT32) Example Sketch GitHub (Design Files & Example Code) need SD Library ???

scheme skema LCD Shield for Arduino for complete reference, visit this web : http://www.hobbytronics.co.uk/arduino/arduino-shields

scheme skema keypad shield for arduino coding example : // include the library code: #include // initialize the library with the numbers of the interface pins LiquidCrystal lcd(8, 9, 4, 5, 6, 7); void setup() { // set up the LCD's number of columns and rows: lcd.begin(16, 2); // Print a message to the LCD. lcd.setCursor(0,0); lcd.print("LCD Key Shield"); lcd.setCursor(0,1); lcd.print("Press Key:"); } void loop() { int x; x = analogRead (0); lcd.setCursor(10,1); if (x < 60) { lcd.print ("Right "); } else if (x < 200) { lcd.print ("Up "); } else if (x < 400){ lcd.print ("Down "); } else if (x < 600){ lcd.print ("Left "); } else if (x < 800){ lcd.print ("Select"); } } daftar pustaka : http://osepp.com/products/shield-arduino-compatible/16x2-lcd-display-keypad-shield/

teks dari serial port (data teks dari komputer) untuk ditampilkan di lcd dgn arduino bisa kah? simak program ini : #include LiquidCrystal lcd(2,3,4,5,6,7); String textFromSerial =""; void setup() { lcd.begin(16,2); lcd.clear(); lcd.setCursor(0,0); lcd.print("Data FromSerial"); Serial.begin(9600); } void loop() { while(Serial.available()>0) { char data = Serial.read(); if(data == '\n') { lcd.setCursor(0,1); lcd.print(textFromSerial); textFromSerial=""; } else{ if(data!='\r') { textFromSerial += data; } } } } lalu sambung arduino dengan LCD nya ketik codingnya bila sukses akan tampil sepeti dibawah ini
