The PCB must be mounted floated, otherwise key presses don't work reliable. Connect pins 3 and 4 on connector P1 for 16-pin button mode. Smaller keypads with less pins may work, but are not tested.

This is a library for the Arduino IDE that helps interface with ST's VL6180X time-of-flight distance and ambient light sensor. The library makes it simple to configure the sensor and read range and ...

Abstract: Mobile robots build on accurate, real-time mapping with onboard range sensors to achieve autonomous navigation over rough terrain. Existing approaches often rely on absolute localization ...

Since Philadelphia is arranged on a grid system, the mostly one-way roads are easy to navigate. Helpful maps are posted along street corners across the city – watch for the "Walk! Philadelphia" signs ...

Chicago's eastern boundary is formed by Lake Michigan, and the city is divided by the Chicago River into three geographic sections: the North Side, the South Side and the West Side. These sections ...

Abstract: In this paper, we analyze the working principle of an arduino. These days many people try to use the arduino because it makes things easier due to the ...
