[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

but we can also utilize this Arduino based speed sensor in scientific experiments to study motion, acceleration, or friction by measuring the speed of different objects in a controlled environments.

it was time to build the rest of the metal detector. Look ma, no MCU! The sensor coil was made by salvaging the wire from an old fluorescent lamp ballast and winding it around the lid of a bucket ...

The UNO is one of the most popular boards in Arduino family and a great choice for beginners. Ultrasonic Sensor: These are the sensor that use ultrasonic waves to detect objects or to measure the ...
