Choosing the Right Arduino Timer: A Practical Guide for Precise Timing and PWM
When you need exact timing or custom PWM on an Arduino Uno, you’ll likely touch the hardware timers. This post walks through the three timers, shows a concrete example of using Timer1 for a 1 kHz control loop, and explains how to avoid common pitfalls and conflicts with core libraries.
Connecting an Arduino Uno to an MPU6050 via I2C: A Step‑by‑Step Guide
Learn how to wire an Arduino Uno to an MPU6050 accelerometer/gyroscope over I2C, upload a minimal sketch, verify serial output, and troubleshoot common pitfalls in a clear, step‑by‑step guide.
Stop Using delay(): Mastering Non-blocking Timing in Arduino
Stop freezing your Arduino projects. Learn how to replace blocking delay() calls with millis() to handle multiple tasks like blinking LEDs and reading sensors simultaneously.
Arduino delay() vs millis(): Non-Blocking Scheduling in Practice
delay() freezes the whole sketch, not just one task. Here is how millis()-based elapsed-time checks let a blink pattern and a debounced button run together — and what that costs.
Implementing Non-blocking Timing in Arduino with millis()
Learn how to replace the blocking delay() function with millis() in Arduino to enable multitasking and responsive sensor polling.
Preventing EEPROM Wear: Managing Non-Volatile Storage in Arduino
Learn how to use Arduino's EEPROM for non-volatile storage without destroying your hardware. We cover the 100k write limit, the critical difference between write() and update(), and how to handle multi-byte data.
Architecting High-Frequency Pulse Counting with Arduino External Interrupts
Learn how to implement high-frequency pulse counting on Arduino using external interrupts, volatile variables, and atomic access to prevent data corruption and pulse loss.
Boost Arduino ADC Accuracy with the 1.1 V Internal Reference
Using the 1.1 V internal reference on an Arduino boosts ADC resolution from ~4.9 mV to ~1.1 mV per count. Pair it with a 5:1 voltage divider, add a 0.1 µF capacitor, and you can read a 0‑5 V sensor with roughly 4.5× more precision—perfect for temperature probes and precision analog work.
