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 is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

H Bridge configuration is commonly used in electrical applications where the load needs to be driven in either direction. A typical H-Bridge structure is shown below; The current flows through the ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector type ...

So your electronic hobby skills are coming along quite nicely but you’re not very comfortable doing more than blinking a few LEDs. Now’s a good time to try something new by driving a couple of DC ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia ...
