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 ...

2.2 Microcontroller 8051 The Microcontrollers are devices with features of a computer system on a single chip, RAM, EPROM memory, Central Processing Unit (CPU), communication ports I / O software ...

We’ve been loving the variety of entries to the 2025 One-Hertz Challenge. Many a clock has been entered, to be sure, but also ...

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.

The microcontroller then toggles I/O Pin 1 and I/O Pin 2, resulting in a piezoelectric voltage of −15V for an effective 30V p-p. These cycles are repeated to generate an alternating voltage with the ...

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.
