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 GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...

All you generally need is the Arduino IDE, which already includes most of the popular libraries for interfacing with ...

[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...

line called for by the LCD protocol. This means you don’t lose any extra pins. Another way to uses the displays with Arduino is to use a smart controller for TFT screens.

To link a standard 16×2 LCD directly with the microcontroller, 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 ...

Software-wise, the Arduino sketch is pretty straightforward with less than 100 lines. So if you want to modify it to add more fans, change the message on the LCD, or use a different temperature ...

I settled upon the LCD display. The displays being used in Arduino projects were interfaced with a lot of I/O pins and code space, neither of which are in great supply on the Atmel chips. I felt that ...
