Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Although the Altera MAX IIZ CPLD is a digital programmable logic device, it is versatile enough to control analog systems. This article shows how MAX IIZ CPLDs – alone or with a few passive ...
