Learn how to design a microcontroller circuit that is secure, reliable, and scalable with this article. Find out how to choose the right microcontroller, design the power supply, connect the ...

Learn how to choose, use, and optimize microcontrollers for electrical circuit design. Discover the tools, techniques, and best practices for circuit design with microcontrollers.

The 4- to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes, ...

Before such chips were available, I designed my own solid state circuit breaker for just such applications, and it still offers many advantages. The design uses two bipolar transistors, a P-channel ...

I find that circuit more useful than using a microcontroller interruption on edge falling, as slew rate and voltage drop threshold can be tuned with the components. About performance, some PNP ...

The complete circuit (Fig. 2) is powered by two AA batteries. Every n seconds (or even hours), the microcontroller decides to see if the battery level is over or under 2.2 V.
