Arduino Tutorial – DS3231 Real Time Clock

In this tutorial we will learn how to use DS3231 Real Time Clock with the Arduino.   About the DS3231 Module: The DS3231 is a low-cost, Real Time Clock Module which can maintain hours, minutes and seconds, as well as, day, month and year information. The module can work on either 3.3 or 5V. The battery input is 3V and a typical CR2032 3V battery can power the module and maintain the information for more than a year.  

Arduino Tutorial – How to use DHT11 and DHT22 sensors

In this tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity. And we will see the value output of the DHT sensors on both the serial monitor and the LCD screen.The LCD screen component is optional. With this tutorial you can also print on a serial monitor. Code and circuit diagram are compatible within both sensors.   The DHT sensors have four pins, VCC, GND, data pin and a not connected pin which has no usage.   From left to right: 1 – VCC (5V) 2 – Signal 3 – NC…

Arduino Project – Make a Low Cost Robotic Hand with Wireless Controlled (using nRF24L01)

In this tutorial, we will learn how to make a robotic hand. And how to controlled it via wireless. We will control 5 servo motor using with 5 pcs flex sensor. Also we will controlled robotic hand using with nRF24L01. This video shows the low-cost “robotic hand” construction. You can get excellent results with better flex sensors and servo motors. Created the flex sensors myself.  

Arduino Project – Remote Controlled Robot Car (TV – Infrared Remote (IR))

In this tutorial we will learn how to control robot car with using TV or IR remote. Also we will use L298N H-bridge motor drive and Infrared Remote (IR) receiver.   IR library and tutorial: Infrared (IR) controls are often used in most electronic devices. The 38 kHz infrared receiver we use in the project demodulates the signal it receives and sends the button code to the Arduino. We can use with this receiver as long as different brand and model remote controls have 38 kHz carrier signal. The receiver has 3 pins. These are GND – VCC – Signal…

Arduino Project – Programmable Robotic Arm (Record and Repeat of the Servo Positions)

In this project tutorial we will learn how to make programmable robotic arm. I used 4 DOF simple robot arm for this project, but you can use any robot arm. For example you can use cardboard, hot glue and micro servos for create simple robot arm.   I used 3 pcs micro servos and potentiometer, but you can add more you want. I also used two buttons. One of the buttons is for recording the servo positions, and the other is for restarting recorded servo positions. The code can be changed, if you add more component so make changes it….

Arduino Tutorial – Touch Screen TFT LCD Tutorial (First review before the next projects)

In this tutorial we will learn how to programming the TFT LCD Touch Screen. I used 2.8″ TFT Touch Display ILI9325 Module and Arduino Uno for this tutorial. The topics we will view in this tutorial, Required Libraries, Add Text, Text Color, Font Size, Print Text, Create Button, Button Click, Add Frame, Draw Rectangle and Background Color.  

Arduino Tutorial – Talk with your Arduino Board using with Voice Recognition Module

In this tutorial we will learn how to talk with the Arduino Board. For this we will use the Voice Control Module. So, we can use this module to control motors, lights and robots.Also, we will use software for record our voice commands. I used the Access Port Software for send HEX commands from Windows to the USB module. MAC users can use the CoolTerm Software for the record commands.  

Arduino Tutorial – The Arduino talking! How is it? Connect speaker and play audio file

I this tutorial we will learn how to play audio files with the Arduino. For this we will use speaker. Also we will use SD card module for keep the audio files. After this tutorial you can make mini mp3 player using the Arduino.   About the SD Card Module Adapter: The module (MicroSD Card Adapter) is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files.
