The Arduino Esplora is a ready-to-use, easy-to-hold controller that lets you explore the infinite possibilities you have in the world of Arduino, without having to deal with breadboards or soldering.

In last week's installment, we showed how to get started with Csound. This week we take it to the next step by constructing a homemade MIDI controller circuit and use the new device to control Csound ...

While cruising the Internet one day, [Raj] found a really cool pair of RF transmitters and receivers manufactured by Dorji Applied Technology. These modules – the DRF5150S and DRF4432S – work just ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

With their cheap price tags, massive I/O provisions, and low power consumption, microcontrollers like the uber-popular ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

In Part 1, we covered the basics ofsensors and the characteristics youmust keep in mind when using them in designs. However, there isan enormous range of specialist sensors developed for ...

Hamster wheels, or running wheels are exercise devices used primarily by hamsters and other rodents, but also by other animals when given the opportunity. Hamster ...
