Real-World Interfacing: Connecting Microcontrollers to the Physical World

Reading Time: 16 minutesIntroduction: From Code to the Real World Up until now, we’ve been working inside the microcontroller. Now it’s time to look outwardly at the connections we can make to a microcontroller with other devices. In Section 1, we explored the fundamentals using the Arduino Uno—learning how to write code, control pins, and begin thinking like […]

Microcontroller 101: A Brief on GPIO, Timers, ADC, PWM, and Interrupts (PIC18F4525)

Reading Time: 50 minutesIntroduction In Part 5, of the Circuit Component Super Series, we introduced microcontrollers as the control layer — the decision-making core that transforms simple circuits into intelligent systems. Now it’s time to go deeper and understand how it works internally. This article breaks down the fundamental building blocks you’ll encounter in nearly every microcontroller project: […]
