This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

Speech synthesis has been around since roughly the middle of the 20th century. Once upon a time, it took remarkably advanced hardware just to even choke out a few words. But as [atomic14] shows ...

We created a comprehensive ESP32 CAM Telegram bot tutorial that can capture images and record custom-duration AVI videos, ...

Many small microcontrollers require so little power that often they can draw what they need through their loads. This can simplify a system, reduce its cost, increase its reliability, and provide ...

It's safe to say that BITalino isn't your average DIY electronics board. For starters, the sensors that spring from the main unit (which comprises the microcontroller, Bluetooth module and power unit) ...

[Scott] was driving in the pouring rain behind a car with its blinkers on when inspiration struck. He had previously created a simple communications system using his sound card that allowed him to ...

In its introductory blog post, the company explains that today’s Raspberry Pis are already often used alongside a smaller microcontroller: The Raspberry Pi takes care of heavyweight computation, ...
