Getting Started with SimulIDE and Arduino

I was looking for an alternative to Tinkercad to simulate building, coding, and running Arduino projects. SimulIDE Circuit Simulator seemed like an ideal candidate. SimulIDE is a simple real time electronic circuit simulator, intended for hobbyist or students to learn and experiment with analog and digital electronic circuits and microcontrollers. It supports PIC, AVR , Arduino and other MCUs and MPUs. I installed it from Flathub (SimulIDE). It worked well. It is easy to understand and work with. It’s also easy for a beginner to pick up and start designing circuits in 5 minutes. I tried a few basic circuits. Then I tried the Blink circuit and Fade circuits based on Arduino. Unlike previous ones, this one included building a firmware and loading it. To make it complex, I was also using the Flatpak version of the Arduino IDE. Then I found two options Load Firmware in SimulIDE In this option, we will build the software in the Arduino IDE. Compile it. Once it generates a firmware (a HEX…
