In our last session we looked at the basic structure and operation of a microcontroller (MCU). Now let’s look at some of the hardware (peripheral circuitry) required to support the microprocessor. In ...

Microcontrollers existed before the Arduino, and a device that anyone could program and blink an LED existed before the first Maker Faire. This might come as a surprise to some, but for others PICs ...

In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it ...

Arithmetic logic unit (ALU), which performs computation. Registers needed for the basic operation of the CPU, such as the program counter (PC), stack pointer (SP), and status register (SR). Further ...
