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 ...

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, ...

When it comes to performance, there's a world of difference between the Raspberry Pi and Arduino ... you'll also need an I2C module to convert your LCD into an I2C device (so it uses fewer ...

These days, you could be forgiven for thinking driving an LCD from a microcontroller is ... Instead, [Ivan] decided to drive it directly from an Arduino Uno. This is easier said than done.

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 ...

Arduino has launched ... as well as two SPI and two I2C serial ports. Finally, the new board includes a 12-bit analog DAC and operational amplifier. Keeping the pinout, voltage and form factor ...
