The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

From circuit simulation to embedded firmware testing and PCB design, Proteus lets you see how hardware and code work together ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

Integrating processors, sensors, and data exchange functionality into everyday objects, the Internet of Things (IoT) pushes computing capabilities far beyond desktops and servers, weaving computation ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...

One reason of Electromagnetic compatibility (EMC) problems with microcontrollers is poor power supply decoupling. A correct and sufficient way of decoupling power supply lines is necessary in order ...

Battery-charger-control designers face a fundamental choice: to use a part from the rich selection of dedicated charge-control ICs available from many vendors or to use a programmable microcontroller.

Following much scrutiny, analysis and debate, judging is complete in the Electronics Weekly/Microchip PIC10F microcontroller circuit design competition. The Electronics Weekly tech team spent more ...
