2x L298 H-Bridge Dual Motor driver project can control two DC motors connected to it.  The circuit is designed around popular dual H-Bridge L298 from ST. Motor supply 7V To 46V DC, Load 2Amp Each Channel. Features Motor supply V2: 7 to 46 VDC Logic Supply V1 : 5V DC...

An ultrasonic parking sensor project from Ch00ftech: After electing to use the PING))) sensor exactly as directed, I needed to build the rest of my circuit.  I wanted to build something robust that would mount nicely on the wall of my dad’s garage.  Figuring that the sensor...

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. by Oyvind @ build-electronic-circuits.com PNP Transistor – How Does It Work? -...

A geeky Christmas decoration made with 56 LED Neopixel and controlled via an Arduino Micro board: Let’s take a look, therefore, at the project’s electrical section, that is essentially composed of a set of 56 Neopixel LEDs, that have been arranged so to form two concentric stars;...

In this video tutorial educ8s.tv shows us how to load bitmap graphics in our Arduino Touch Screen projects using Adafruit's GFX library. The procedure that I am going to describe works with all the color displays that are supported by Adafruit’s GFX library and by the displays that...

by Susan Nordyk @ edn.com: A wide input range of 4.5 V to 40 V enables the TS3004x series of DC/DC synchronous buck regulators from Semtech to work in a wide range of applications, including industrial, telecommunication, and consumer. The current-mode TS30041 and TS30042 furnish 1...

by Jan Buiting @ elektormagazine.com: In a stint of list-o-mania TE Connectivity have slapped five environmental sensors on a single board called MEAS for plugging onto the Arduino/Genuino 101 and Uno R3. Here goes in telegram style. MEAS: five weather sensors on one Arduino shield...

Sergey Kiselev designed and built an Intel Quark D2000 micrcontroller based Environmental sensors board: This is a fairly small (51 x 51 mm) board, equipped with a low power Intel Quark D2000 microcontroller, and several sensors (accelerator, temperature, humidity, atmospheric...
