Interfacing Nokia LCD With Arduino
For this project I have been using freeduino which is having atmega 8 microcontroller. Atmega328P, Fully compatible with Arduino UNO Board. This board has 14 digital pins, 6 analog pins, 8 pin Power connector has 5V, 3.3V GND and Reset connection. SCL and SDA lines are also made available in the connector. 100uf/16V capacitors are used instead of 47uf as in original UNO design for improved filtering. Power selection is automatic, it can be from USB or external power adopter.
This board uses Atmega16U2 microcontroller for software based USB to serial converter and comes Atmega328P-PU chip as main controller for projects.
As this board is 100% compatible with Arduino UNO R3, You don’t have to change any thing in Arduino IDE. It will work as UNO R3 always with lower cost.
Original Arduino UNO design is fallowed so there is no difference, made in most modern automated factory for great quality and reduced cost. Anti static package and a good quality FREE USB cable 52 CM long comes with this pack.
NOKIA 5110 LCD
This is a quick tutorial for our 84×48 pixel monochrome LCD display. These displays are small, only about 1.5″ diameter, but very readable due and comes with a backlight. This display is made of 84×48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well. The display driver is a PCD8544 chip, and it runs at 3.3V so you’ll need a 3V supply handy
