Boris Landoni writes about a new open source project a DC motor controller with control LEDs: The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container with 15 staggered pins; it has two...

Here is a nice tutorial @ raspberrypi.org on how to control a DC motor using Python. In this guide, you'll be controlling two motors from your Raspberry Pi using Python on the desktop. First, it's best just to learn how to control the motor. Then, once you have it working, you could...

Susanne Nell @ edn.com has a design idea on how to measure high dc currents. To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods...

Michael Dunn has designed a circuit that is able to double the input voltage and breaks DC path. I once needed a voltage doubler circuit with no DC leakage path between input and output, and ended up devising this unusual 556- (dual 555 timer) based circuit with a "floating" voltage...

Ahmad Al-Shalabi and Bassma Karbouj show us how to control a DC fan using easy to find components. The fan works when temperature reach into pre-specified threshold. The purpose of this project is creating a cooling system by controlling in a DC fan in a simple way without using...

Tiny low current 9 VDC Regulated Power supply designed around bipolar transistor and zener diode. The circuit is known as series voltage regulator or emitter follower voltage regulator. The unregulated supply fed to input and the circuit regulate the voltage and provide constant 9V...

Measure the DC power consumption of your devices on the cloud @ adafruit.com Controlling the electrical consumption in your home is one of the most important thing you can do, both because of environmental concerns & to reduce the electricity bill at the end of the month. There...

DC Motor Direction Control project offers direction control using digital logic gates and a DPDT relay. Features Supply input 12 VDC @ 75 mA Power LED DC Motor Direction LED Yellow/Green Relay Output: up to 7 A Onboard tactile switch for direction control Relay based...
