Servo motors are great devices that can turn to a specified position. Usually, they have a servo arm that can turn 180 degrees. Using the Arduino, we can tell a servo to go to a specified position and it will go there. As simple as that! Here we will see how to connect a servo motor and then how to turn it to different positions.
Hobby servos are the easiest way to get going with motor control. They have a 3-pin 0.1″ female header connection with +5V, ground and signal inputs. The motor shield simply brings out the PWM output lines from Arduino pins 9 and 10 to two 3-pin headers so that its easy to plug in and go. They can take a lot of power so a 9V battery wont last more than a few minutes! The nice thing about using the onboard PWM is that its very precise and goes about its business in the background. You can use the built in…
Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino or Genuino board. The ground wire is typically black or brown and should be connected to a ground pin on the board. The signal pin is typically yellow or orange and should be connected to pin 9 on the board. The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the board. I…
Servo, can be powered by another power source without Arduino power. Only thing important here is that all the GND are connected to each other. Like this you can add as many servo motors as you want. Important! If you will use high voltage battery and you want give power to arduino with same power source, you need to put a 7805 voltage regulator in, and make a parallel circuit for that too.
In this tutorial you will be creating an application for controlling a servo motor. Use slider in your application and move to servo motor from 0-180.
This is a very useful chip. It can actually control one motor independently. We will use in its entirety the chip in this tutorial. Pins on the right hand side of the chip are for controlling a one motor. Pins on the left hand side of the chip are for controlling second motor. You can run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D.
In this project we will transform an RC toy car to bluetooth controlled Arduino car!
Sound sensors can be used for a variety of things, one of them could be turning lights off and on by clapping. Today however we are going to use hook up the sound sensor to an array of LED lights which will beat with music, clapping or knocking.
This Tutorial is for anyone getting started with arduino. We will be building an obstacle avoiding robot that uses an ultrasonic HC SR-04 sensor to detect objects and L293D Motor Driver.
This is Arduino Basic Tutorial for beginners. We will learn in this video “How to install and use Arduino Software”
Arduino libraries are a convenient way to share code such as device drivers or commonly used utility functions. This guide details how to install libraries on your computer. There are two general types of Arduino Libraries: Standard Libraries User Installed Libraries Where to Install your Libraries? Your sketchbook folder is the folder where the Arduino IDE stores your sketches. This folder is automatically created by the IDE when you install it. Using Libraries One of the best features of the Arduino project is the ability to add on pre-crafted libraries that add hardware support. There’s tons of…
Arduino basic tutorial “analogRead” Serial Monitor with Potentiometer. Reads an analog input on pin A0, prints the result to the serial monitor.
Arduino Basic Tutorial digitalRead Serial Monitor with Button. Reads a digital input on pin 2, prints the result to the serial monitor. When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and reads as LOW, or 0. When the button is closed (pressed), it makes a connection between its two legs, connecting the pin to 5 volts, so that the pin reads as HIGH, or 1.

We will provide Arduino communication via bluetooth with the previously defined sentence commands in the Android application. You can use this project in home automation systems. For now we will use the ready-made application. In the following days I will publish a tutorial on creating an application.
In this Arduino Tutorial we will learn how the HC-SR04 Ultrasonic Sensor works and how to use it with the Arduino Board.
