Arduino LED Tutorial | Control Standard LEDs Like a Pro
LEDs are the most fundamental Arduino output — but there's more to them than just blink! This comprehensive tutorial covers resistor calculation, multiple LED control, PWM brightness dimming, and best practices for driving LEDs from Arduino pins.
💡 What you'll learn and more topics to research:
• How LEDs work and why resistors are essential
• Calculating the correct resistor value (Ohm's law)
• Controlling LED brightness with analogWrite() / PWM
• Driving multiple LEDs with shift registers
• Common mistakes and how to avoid burning out LEDs
