Both can connect to the internet, run applications, and interface with sensors, but they represent vastly different approaches to IoT system design. This guide helps you make the right choice by comparing architecture, cost, power consumption, software complexity, and real-world use cases.https://toorun.dev/posts/how-to-choose-the-right-microcontroller-for-your-project/Mon, 24 Aug 2026 10:00:00 +0000https://toorun.dev/posts/how-to-choose-the-right-microcontroller-for-your-project/How to Choose the Right Microcontroller for Your Project Choosing the right microcontroller is one of the earliest and most impactful decisions in any embedded project. Get it right, and development flows smoothly. Get it wrong, and you might find yourself redesigning hardware, fighting inadequate peripherals, or scrambling for parts during production. This guide walks through the key factors engineers should evaluate when selecting an MCU, with practical examples and a selection checklist you can use immediately.https://toorun.dev/posts/pwm-audio-synthesis-voice-generation-embedded-systems/Mon, 17 Aug 2026 10:00:00 +0000https://toorun.dev/posts/pwm-audio-synthesis-voice-generation-embedded-systems/PWM Audio Synthesis: How to Generate Sound and Voice in Embedded Systems Using Pulse Width Modulation If you have worked with PWM (Pulse Width Modulation), you probably know it for motor control, LED dimming, or switching regulators. But PWM can also generate audio signals: beeps, tones, melodies, and even human voice playback. This technique is common in cost-sensitive embedded products where a dedicated DAC (Digital-to-Analog Converter) is too expensive, too power-hungry, or simply unnecessary.
