The Arduino UNO™ is equipped with 6 analog inputs. Some projects call for more analog inputs, e.g. sensor- or robot projects. This shield only uses 4 I/O lines (3 digital, 1 analog) but adds a whopping 24 inputs, so in total you have 29 analog inputs at your disposal.   Features 24 analog inputs uses…

Breakout board based on the 434 MHz RFM69HCW transceiver module. It uses the SPI (Serial Peripheral Interface) interface to communicate with Arduino or another host microcontroller, operates in the ISM radio band (Industry, Science and Medicine) which does not require a license. It is able of transmitting up to 100 mW at 300 kbps, covering…

Compact and handy, this air compressor allows you to inflate tyres of bicycles, motorcycles, cars and, thanks to the nozzles provided, even dinghies, inflatable boats and balls. The device can also be used as a torch. Power supply via cigarette lighter socket (12V); maximum pressure 8 bar (116 PSI), power: 30 w, air hose length:…

This quadrature encoder works with our micro metal gearmotors, 42×19mm wheel, and extended bracket to measure the rotation speed and direction of the wheel. With twelve teeth on the wheel, the system provides a resolution of 48 counts per revolution, which corresponds to a linear resolution of just under 3 mm or 1/8″   Technical…

This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 297.92:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm extended…

This set includes sensor boards and reflective wheels to add quadrature encoding to two micro metal gearmotors with extended back shafts (motors are not included with this kit). 3-tooth and 5-tooth encoder wheels are included to provide options of 12 counts per revolution and 20 counts per revolution of the motor shaft (to compute the…
