for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine ...

[Kaushlesh Chandel] prototyped a few projects on his Arduino ... LCD. It looks like he’s using the 4-bit mode for addressing that display, which leaves you with quite a few pins (both digital ...

Adafruit has this week announced the arrival of the new Arduino ... pins hooked up to one microcontroller. Adafruit explains a little more about the new breakout board. You just found the perfect ...

Some Arduino boards feature the I2C pins in different places, and you can check out the full hardware requirements for all Arduino boards on the Wire Library Reference page. This gives you access ...
