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.

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 design, based on a Maxim MAX220 RS-232 driver/receiver IC, allows you to increase the number of USARTs (universal synchronous, asynchronous receiver/transmitters) available on a microcontroller.

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 ...

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 ...

[Bill Porter] has a tip for designing circuits that have multiple connections to a single microcontroller UART. This stemmed from a review of a friend’s circuit design that used the UART in the ...

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

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.

Electrical and electronic circuits are around us. From our mobile phones to security systems, electronic circuits are everywhere. Designing a circuit follows a step-by-step procedure. Most of the time ...

SAN JOSE , Calif., April 27, 2010 — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today ...
