        <title>What Is Embedded Programming? A Plain-English Introduction</title>
        <link>https://mybytenest.com/tech/what-is-embedded-programming.html</link>
        <description>Most of the computers in your life are not the ones you sit in front of. They are inside your microwave, your car, your coffee machine, your insulin pump. Embedded programming is how those computers get told what to do.</description>

        <title>C vs C++ for Embedded Systems: An Honest Comparison</title>
        <link>https://mybytenest.com/tech/c-vs-cpp-embedded-systems.html</link>
        <description>The debate is older than most firmware engineers. C is the historical default; C++ has quietly taken over huge parts of the industry. Here is when each one is actually the right choice.</description>

        <title>Bare Metal vs RTOS: When to Use Each</title>
        <link>https://mybytenest.com/tech/bare-metal-vs-rtos.html</link>
        <description>An RTOS sounds professional. Bare metal sounds primitive. Neither intuition is reliable. The right choice depends on concurrency, RAM, timing, and team size — and most firmware projects get this wrong in the same direction.</description>

        <link>https://mybytenest.com/tech/garage-door-opener-esp32.html</link>
        <description>An ESP32 that does two things: pulses a relay across the existing garage-door wall-button contacts to trigger the door, and reads a reed switch on the floor track to know whether the door is currently open or closed. MQTT-controlled for Home Assistant, with a tiny web UI as fallback.</description>

        <description>An ESP32 paired with the cheap MFRC522 RFID reader and a 12 V solenoid lock. Authorized cards open the lock and log the access (who, when) to a server. Unknown cards trigger a buzzer and log a denied attempt. About $35 in parts.</description>

        <description>An ESP32 streams MP3 internet radio stations through a MAX98357 I2S audio DAC into a small speaker. A rotary encoder picks the station, an OLED shows the now-playing string, and the whole thing fits in a coffee-mug-sized enclosure. Sounds genuinely good for $40 in parts.</description>

        <description>An ESP32 reads the PMS5003 laser particle sensor and drives a 12V PWM fan through a MOSFET. Speed scales with measured PM2.5: quiet when air is clean, ramping up when pollution rises. Reports live readings to MQTT. Around $50 in parts including the fan.</description>

        <description>A NEMA17 stepper rotates the tilt rod of standard horizontal blinds. An ESP32 schedules opens at sunrise, closes at dusk, and adjusts based on a photoresistor reading the actual sunlight. The blinds you already own become smart for $50 instead of $300 per window.</description>
