Arduino Project – Create Phone Application and Control the Arduino Robot via Bluetooth!

In this tutorial we will learn how to control the Arduino via bluetooth using the android application. First, we will make the robot car for control it. And, we will use Bluetooth module (HC05 or HC06) for the communication. And last, we will create the android application for sending commands to the robot car.   We will use MIT App Inventor for create the android application. Also, I will use 3D printed chassis for the robot car. But, you can use any chassis. If you want, you can download my 3D model and use it.

Arduino Project – A $5 Robotic Hand! Make low budget robotic hand!

In this project we will make a Robotic hand with a $ 5 Plastic Robot Grabbing Hand. As you know, I have a 3D printer and I could make this robotic hand with 3D printer but I shared this video because everyone can make a robot arm. Some friends may not like this video but everyone’s budget is not enough to make a robotic hand with a 3D printer. Thus, everyone can experience the robotic hand. Teachers, students and everyone else can create a low-budget robotic hand.  

nRF24L01 Insufficient Power Problems and Better Range Distance

Many users have had trouble getting the nRF24L01 modules to work. This module is unfortunately not perfect!   Interruption of Communicate No communication at all Low range   Many times the problem is that the 3.3V Power to the module does not have enough current capability, or current surges cause problems.   Solder a 3.3 uF to 10 uF capacitor directly on the module from VCC to Gnd.  

L293D Motor Shield Upgrade for the High-Torque Stepper Motor

In this tutorial we will learn how to use a high-torque stepper motor with the L293D motor drive shield. I used a high torque stepper motor with the L293D motor driver, so the L293D integration overheated. The cause is high current requirement. I modified the L293D Motor driver shield to solve this problem.  

Arduino Tutorial – Turn on / off anything at a specific time. (Trigger a Relay with DS3231 RTC)

In this tutorial we will learn how to turn on / off anything at a specific time. For this we will use DS3231 RTC module and Relay module. Like time switch. Trigger a Relay with DS3231 Real Time Clock.  

Music Reactive LED Strip Light with 3D Case DIY – Arduino and Sound Sensor

Building a LED strip light that visualizes all sounds and music, using simple components and some basic arduino programming. Build a simple driver circuit on a breadboard to amplify the Arduino output pins to provide the necessary current to the LEDs, and create your own light show! Also create a 3D case to be safe and portable.  

Grabber (Crab) Robot – Arduino | Bluetooth | Remote Control via Application

In this project we will make a fun robot. This robot looks like a crab. With a phone application you can control the robot via bluetooth and grab (pick up) anything that is on the ground. In this project you can learn to create an android application and control Arduino via the HC-06 or HC-05 bluetooth module.  

How to Display a Simple Analog Clock on the OLED Screen | Arduino

In this tutorial we will learn how to display a simple analog clock on the OLED screen. For this tutorial we will use OLED 128×64 I2C SSD1306 display, DS3231 Real Time Clock Module and Arduino Mega. For this tutorial we will use the source code and libraries created by Rinky-Dink Electronics.  

Line Following / Follower Robot Car with Infrared IR Sensor | Arduino

In this tutorial we will learn how to make a “line following / follower robot”. We will use 4 channel infrared (IR) sensors for this. And we will use the Arduino board for control. For motors we will use the L298N motor driver.  

Arduino Balance – Balancing Robot | How to Make?

In this tutorial we will learn how to make Arduino balancing (balance) robot that balances itself.  

XY Plotter Drawing Robot Machine | Arduino | Polargraph

In this tutorial we will learn how to make X Y Plotter Drawing machine. With Drawing Robot you can draw images on wall, panel or A4 paper. You can print pictures or print text. All required hardware for this project are listed below. We will learn how to install and use the Polargraph program for robot control. Video editing of this project took a lot of time. I hope the video will be useful to you. If you want, you can subscribe to the my channel for support.  

Using Arrays: Arduino Course for Absolute Beginners

For Loop Iteration: Arduino Course for Absolute Beginners

There are few functions so useful that you find them everywhere. The ‘for loop’ is an example of this type. A For Loop repeats an action for a specified number of iterations, reducing the lines of code that need to be written thus making the programmers life easier.   In this example we are setting out to make a row of LEDs light up somewhat similar to Kit in Knight Rider.  

If Statement Conditionals: Arduino Course for Absolute Beginners

In the last lesson we learned about the “If statement”. The “If statement” was the perfect choice for setting up instructions to run only when certain conditions are met. “If 30 seconds has passed – stop the heating element” or “If the sensor perceives a wall – turn 180 Degrees”. This lesson will expand on this amazingly useful function and show you how to stack different conditions to meet the flexibility you will want in your designs.  

Fade an LED: Arduino Course for Absolute Beginners

Lets expand the repertoire of output that we can use by looking at the function analogWrite(). I experienced much confusion with analogWrite(), because I suspected that it had to do with the analog pins on the Arduino. The function, however, has nothing to do with the analog pins. There are 5 pins on most Arduino boards marked with an ‘~’ next to the pin number – these pins can be invoked to rapidly change the power being applied at the pin – this is a technique called pulse width modulation (PWM).  

How to read voltages with analogRead(): Arduino Course for Absolute Beginners

In the last lesson you learned about using the analogRead() function to collect data from a sensor connected to one of the Arduino’ analog pins. The range of data we received from the analogRead() function, was mapped from 0 to 1023. What if we wanted to know the actual voltage being applied at the pin?  

analogRead() and the Serial Port: Arduino Course for Absolute Beginners

Knowing if something is on or off can be extremely useful, but often you will want to know more. How bright is the light? How fast is the satellite moving? These types of answers are often analog – they cover a large range of values, not just on or off.   The Arduino handles analogs inputs with 6 dedicated pins, labeled A0 through A5. These pins have access to an analog-to-digital converter, which takes the range of input values and creates a digital version by cutting up the range into tiny pieces. All this is handled behind the scenes –…

digitalRead() and the Serial Port: Arduino Course for Absolute Beginners

As simple as it may seem, knowing when something is either on or off can be a great tool to designing something useful. Answers to the following questions are what this lesson plans to tackle:   Is a button being pressed? Has a switch been turned on? What is my on/off sensor status? When you can answer questions like these, you can implement actions based on the current status – if the button is pressed do this – otherwise, do that. If the sensor is HIGH take this action, otherwise do nothing. You get the gist. But before we can…
