Knobs are a very old and vital form of control, used in radios several hundred years ago and also in modern car interiors. Knob is based on a variable resistance, and the input is a typical analog signal. The resistance varies during rotation, and the input signal varies continuously from 0 to 1023.
Rotary Angle Card helps you to create control panels quickly and easily, and also allows you to interact with other ideas such as twisting a towel.
Rotary Angle card produces digital output between 0 and 1023 with Carduino. The angular range of the potentiometer is 300 degrees with a linear change in value. Rotary Angle Card converts the analog potentiometer reading to digital using the internal ADC converter. The output ranges from 0-1023 and can be read via I2C.
Longan Cards is a unique open source development platform designed by Longan Labs. As a plug and play development platform, Longan Cards allows you to quicky build wide array of prototypes and applications in no time. A full set of Arduino libraries and plenty of example codes are available to play with Longan Cards platform.
