“analogRead(pinNumber);” pinNumber represents the pins where the analog components are connected in Arduino. For example: int sensorvalue = analogRead(A2);. The function is used to program and address analog
To use this meter with an LCD screen, connect the LCD to your Arduino (seeHow to Set Up an LCD Display on an Arduinoif you need instructions). Pin 11 will be used for the LCD, so wire the capacitance meter using pin 8 instead of pin 11. Here’s the code: #define analogPin 0 #...
Arduino shiftIn() receives serial data from parallel to serial converter chips, Saving You Microcontroller Pins. Find out how it works and how fast it operates.
The joystick has two potentiometers, which you connect to analog pins A0 and A1 on your Arduino. The value of A0 corresponds to the X position. The value of A1 corresponds to the Y position. To read these analog values, use the AnalogRead() function. Hardware 1 x Arduino Uno 1 x Ardu...

In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the object to travel between them. With the recorded time and the known distance between ...
A servo motor can draw significant current, so use an external power source (5V) instead of the Arduino's 5V pin. Ensure that the ground (GND) of the servo and Arduino is connected to complete the circuit. This project allows you to control a servo motor using an analog joystick and an...

In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
First we define the output pin (pin 13) and input pin (analog pin 0) with these two statements: const int ledPin = 13; const int sensorPin = 0; We want long LED flashes when lots of light hits the photoresistor and short LED flashes when no light hits the photoresistor. TheminDurat...
