If the analog output (AO) of the module is connected to an analog input (for example A0) on the Arduino you can expect to read a value of 0 (0V) when in its upright position and 1023 (5V) when it is ...

Another project had brought him in contact with some relatively cheap MEMS accelerometers and gyroscopes. He had the idea to create a simple tilt sensor based circuit that would light whatever ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...
