The audio component centers around the SS8550 PNP transistor (Q1) which serves as a driver for the passive buzzer (BZ1). This ...

Most of you know how an NFC tag works. The reader creates an RF field that has enough energy to power the electronics in the ...

Raspberry Pi RP2350 A4 stepping release fixes security vulnerabilities, resolves GPIO erratum, and introduces RP2354 variants ...

Is it possible for a tiny microcontroller to run on a massive 48-V battery? This DIY electronics project makes it happen with ...

Alec Bath is a field applications engineer in the microcontroller division of STMicroelectronics. He has worked at ST since 2000 supporting microcontroller and memory products. Prior to ST, Bath ...

They may seem simpler, but don't be fooled: microcontrollers are perfect for a lot of my more complicated setups for a number of reasons ...

Figure 1 shows how you might configure a microcontroller-based tester, which you can build for less than $500 plus the cost of any external instruments, to test a PCB. The system includes the ...

The Raspberry Pi Foundation has announced the Raspberry Pi Pico, a $4 microcontroller. The computer features the new RP2040, which will also show up in other products, thanks to the foundation’s ...

1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

A microcontroller might contain an embedded processor as part of its makeup, but also combines other computer parts, such as memory and signal registers, in a single chip.

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...
