This project illustrates the use of a microcontroller(MCU) to generate different types of sound. The device uses SST89E54RDA-40-C-PIEMCU, an 8-bit 8051-compatible MCU with embedded SuperFlash ...

The usual way send data from a microcontroller is either over RS-232 with MAX232 serial ICs, crystals, and a relatively ancient computer, or by bit-banging the USB protocol and worrying about ...

For his A-level electronic course work, [Andrew] decided to build a digital sound recorder that doesn’t use a microcontroller. [Andrew]’s build captures audio from an on board microphone at ...

Hot Bots: How Arduino Teaches Kids the Science behind Modern GizmosBut the type of microcontroller that is gaining favor rapidly for creative older children’s projects is known as an “arduino ...

Meet the Raspberry Pi Pico, a tiny little microcontroller that lets you build hardware projects with some code running on the microcontroller. Even more interesting, the Raspberry Pi Foundation is ...

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.

As transistor sizes shrink and switching frequency increases, noise becomes a much bigger problem.

Buzzer Basics: Technologies, Drive Circuits, and Live Sound Demos Attempts to implement readback protection on microcontrollers not designed to provide such protections are bound to fail.
