  • Apply advanced timer techniques like interrupts and pulse width modulation (PWM).
  • Troubleshoot and optimize timer-based projects for precise and reliable performance.

Course content

3 sections • 18 lectures • 1h 15m total length

  • Course Promo1:17

    Master Arduino timers from zero to advanced, replacing delay with non-blocking interrupts, controlling pwm for leds and buzzers, and building timed projects for robotics and automation.

  • Section Intro1:02
  • Introduction4:03

    Explore how Arduino timers enable non-blocking multitasking beyond the delay function. Learn about timer types, prescalers, and configuring timer one on the Uno to blink an led.

  • Design Discussion: Planning a Timer-Based Arduino Application
  • Understanding Timers1:50

    Explore how timers count clock pulses to trigger precise events in microcontroller systems, and compare Arduino Uno timer zero (eight bit), timer one (sixteen bit), and timer two (eight bit).

  • Importance of Timers3:06

    Harness timers to multitask on microcontrollers, avoiding blocking delays and scheduling sensor reads, motor control, and display updates at precise intervals for UART, SPI, and I2C communication.

  • Timer as a Counter3:07

    Discover how an Arduino timer acts as a hardware counter to measure time-based events, enabling delay, millis, microns, and pwm control for LEDs and motors.

  • Introduction to Arduino Timers
  • Prescalar and Interrupts3:24

    Use a prescaler to divide the system clock, slow the timer, and extend its usable time range, then use timer interrupts to trigger an interrupt service routine at set values.

  • Timer ISR Modes1:33

    Explore timer interrupts in Arduino timers, including compare match, overflow, and input capture modes, and see how the ISR triggers on matches, overflows, or external events.

  • Timer Main Registers5:35

    Configure Arduino timers by setting timer counter control registers and prescaler to select mode and speed, then manage tcnt, OCR A/B, and interrupts with the mask and flag registers.

  • Advanced Timer Concepts in Arduino
  • Toggling LED Application pt17:42

    Demonstrates using timer one on an Arduino Uno to toggle an LED every one second, using Tinkercad simulation and pin 13, with a 1024 prescaler and CTC mode.

  • Toggling LED Application pt24:19

    Use timer one in CTC mode to toggle an LED on pin 13 via an ISR. Learn how compare match A and a 1024 prescaler create a one-second interval.

  • Working with Arduino Timers – Practical Applications and Interrupts
  • Summary0:44
  • Reading Material0:37

Requirements

  • Basic familiarity with Arduino programming and the Arduino IDE.
  • An Arduino board (e.g., Uno, Nano, Mega) and a USB cable for connection.
  • Access to basic electronic components like LEDs, resistors, and jumper wires.
  • A willingness to experiment with coding and electronics.

Description

Master Timing Control and Unlock Arduino’s Full Performance Potential

Arduino Timers: Basics to Advance is your deep dive into the most powerful — and most underused — feature of the Arduino platform. Whether you're creating LED patterns, motor controls, or multitasking systems, timers are the key to precision, automation, and professional-level projects.

This course teaches you to take control of Arduino’s internal timing systems using real-world projects, simulations, and low-level coding techniques. From blinking an LED without delay() to managing pulse width modulation (PWM) and interrupts, you'll learn how to make your Arduino projects more responsive, accurate, and efficient.

No filler — just focused, actionable instruction designed to elevate your Arduino programming.

Why This Course Stands Out ?

  • Beyond delay(): Move past basic delays and start building real-time, event-driven systems

  • Real Projects, Real Skills: Apply everything you learn in projects you can use, demo, or expand

  • Master Low-Level Hardware Control: Go under the hood of the Arduino to understand how timers actually work

  • Fast Results: In just over an hour, you’ll gain skills most Arduino users never master

What You Will Learn

  • How Arduino timers work (Timer0, Timer1, Timer2, etc.)

  • Timer registers and configuration for precise control

  • How to create timed events without blocking other code

  • Pulse Width Modulation (PWM) and analog output

  • Timer interrupts for non-blocking control loops

  • Real-world applications: LED fading, buzzer tones, servo control, timed automation

Projects You’ll Build

  • LED blink and fade without delay()

  • Buzzer with precise sound generation

  • Servo motor movement based on timing logic

  • Timed light show using multiple independent sequences

  • Input-triggered timed actions with interrupt handling

Who This Course is For

  • Hobbyists ready to level up their Arduino programming

  • Students needing deeper understanding of microcontroller architecture

  • Professionals designing time-sensitive or multi-tasking Arduino systems

  • Makers working with robotics, automation, or real-time hardware
