This is a smoke and gas sensor on a small circuit board that is designed to work with all of the Arduino boards. It is easy to incorporate into any project requiring only a 5v supply, ground, and an analog input to measure the sensors readings. It can be...

This is a digital temperature sensor module that can be used with any Arduino board. It measures temperatures from -55°C to +125°C and outputs a digital signal that can be read using one of the digital pins on the Arduino. The benefits of...

This is a very popular LCD Keypad shield for Arduino or Freeduino board. It includes a 2x16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Analog Pin 0 is used to read the pushbuttons. The LCD...
