LED Resistor Calculator (with Practical Examples)
The LED (Light Emitting Diode) resistor calculator can help you determine the appropriate resistor value for a LED forward voltage drop and power supply. The resistor is used to limit …
Why is a Resistor Needed for a LED?
A current limiting resistor is used in series with a Light Emitting Diode (LED). In this post we will explain why we need this resistor. LED Current and Voltage Specifications …
Arduino LED Resistor Value Calculator
The Arduino [1] Input/Output (I/O) pins can be used to control an LED and make it blink. It does this, by turning the output pin on and off. Arduino Resistor …
What is the Arduino Nano ADC Sample Rate?
The maximum sampling rate of the Arduino Nano Analog-to-Digital converter is 15 kilo-samples per second or 15,000 samples per second. It’s a 10 bit ADC which means it has 10 bits of resolution. …
ADC Voltage Divider – Calculator and Practical Examples
Introduction When a voltage is input to an Analog-to-Digital Converter, care must be taken that the max voltage spec of the ADC is not exceeded. This page provides a voltage …
