Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...

The LM317T from National Semiconductor is a popular adjustable-voltage regulator that provides output voltages of 1.25 to 37V with maximum 1.5A current. You can adjust the output voltage with a ...

Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...

Having advocated Arduinos for prototype PWM signal generation, I have just discovered a subtlety that might trip up the unwary (amongst which I count myself). The original idea was not to use Arduino ...

Having the right tool for the job makes all the difference, especially for the types of projects we feature here at Hackaday. [Jana Marie] must agree with this sentiment, one of her latest projects ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...

CHANDLER, Ariz., June 18, 2025 (GLOBE NEWSWIRE) -- Evolving security and functional safety demands, coupled with the growing complexity of real-time embedded applications, are driving designers to ...
