In this tutorial, I will show you how to use an Arduino to read temperature from a thermistor and print it on the serial port. A thermistor is a simple electronic component that changes resistance based on the temperature. This tutorial focuses on the simplest and least expensive means for ...
And if your Arduino means there is an ATMega328 MCU, the ADC it has needs the source impedance to be less than 10 kohms. And since your voltage divider has one 1 Mohm as the other resistance, it means that the source impedance is way too high for the ADC to fu...
In the logarithmic graph, RS is the sensing resistance during the presence of Alcohol. While R0 is the sense resistance to clean air. This Sensor is designed to detect Alcohol and has minor sensitivity to Benzine, so this Sensor's resistance will change depending on the concentration of alcohol...
In the start f the code, 5 analog pins of Arduino are initialized to be used with the flex sensors. Than the Vcc from the Arduino and 4.7k ohm resistance is initialized that is used in the circuit. Then the resistance of the straight flex sensor and the resistance at a 90-degree angle...
ESR is the equivalent series resistance of the output capacitor. Iout_maxis the maximum output current of the application. D is the duty cycle from Equation 1. ΔILis the inductor ripple current from Equation 2 or Equation 6. Important Equations for Boost Converter Power Stage ...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
Battery capacity measurement can be useful in many situations. And it is not hard, only requires enough time to discharge battery completely with know resistance and a way to measure voltage in the circuit. Ohm's law will to the rest: I = U / R Let's say
3. Three resistors (depending on your LEDs, the resistor value will be different - check the ratings on the LEDs to see what resistance corresponds to their maximum brightness, without burning them out) 4. A solderless breadboard 5. Some wire, to use as leads from the Arduino to the LEDs...
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
In this tutorial we will learn how to build an Arduino Mecanum Wheels Robot which is capable of moving in any direction. The unique mobility of the robot...
