Bluetooth Controlled 8×8 LED Matrix Sign Board Display using Arduino

Make a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its android application which allows the user to control all the 64 LEDs individually from the mobile phone. This enables the user to create custom designs with ease and display it on the LED display.

Raspberry Pi DHT11 Temperature and Humidity Monitoring

In this tutorial we are going to learn how to interface the popular DHT11 sensor with Raspberry Pi and display the value of temperature and humidity on a 16×2 LCD screen

How to Program Arduino with an Android device

How to Program Arduino with an Android device

You might have used OTG adaptor for connecting Pen drives and game controllers, and give power to small devices. You can do much more things other than powering up your Arduino board with Smart Phone. In this tutorial, we will compile and upload Arduino code using Android Application called “ArduinoDroid” which is completely same as Arduino IDE.

Arduino Color Mixing Lamp using RGB LED and …

Arduino Color Mixing Lamp using RGB LED and LDR

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is change in light in the room. So this lamp will automatically will changes its color according to the light conditions in the room.

Digital Thermometer using a PIC Microcontroller and DS18B20

Generally, the LM35 temperature sensor is used with microcontrollers to measure the temperature because it is cheap and easily available. But LM35 gives analog values and we need to convert them into digital using ADC (Analog to Digital Converter). But today we are using DS18B20 temperature sensor in which we don’t need an ADC conversion to get the temperature. Here we will use PIC Microcontroller with DS18B20 to measure the Temperature.

Tutorial for Beginners – DC Motor Speed Control using Arduino & Potentiometer

DC motor is the most used motor in Robotics and electronics projects. For controlling the speed of DC motor we have various methods, but in this project we are controlling DC Motor speed using PWM. In this project we will be able to control the speed of DC motor with potentiometer and we can adjust the speed by rotating the knob of Potentiometer.

TVOC and CO2 Measurement using Arduino and CCS811 Air Quality Sensor

In this tutorial, we are going to show you that how to sense TVOC and CO2 using CCS811 air quality sensor with Arduino. Also, you will learn to interface CSS811 with Arduino.

Arduino Countdown Timer

Arduino Countdown Timer

Here, in this tutorial we will show you how to make a Countdown Timer using Arduino. Here we are not using any Real Time Clock (RTC) module for getting the time. The time duration is provided by the user with the help of Keypad and 16×2 LCD. And when the timer reaches to Zero, alert sound will be produced with the help of Buzzer.

DIY Arduino Inclinometer using MPU6050

The MPU6050 is an IC 3-axis accelerometer and a 3-axis gyroscope combined into one unit. It also houses a temperature sensor and a DCM to perform a complex task. The MPU6050 is commonly used in building Drone and other remote robots like a self-balancing robot. In this project we will learn how to use the MPU6050 is built an Inclinometer or Spirit Leveller. As we know an inclinometer is used to check if a surface is perfectly leveled or not, they are available either as sprit bubble ones or as digital meters. In this project, we are going to build a Digital Inclinometer which can be monitored using an Android application. The reason for using a remote display like a mobile phone is that we can monitor the values from MPU6050 without having to look at the hardware, this would come very handy when the MPU6050 is placed on a drone or some other inaccessible locations.

Arduino Alcohol Detector Circuit Board

Arduino Alcohol Detector Circuit Board

In this project, I am going to Interface an Alcohol Sensor with #Arduino. Here I have designed an Arduino Shield PCB using EASYEDA online PCB simulator and designer. Arduino Alcohol Detectorwill detect the alcohol level in breath and by using some calculations in code we can calculate the alcohol level in breath or blood and can trigger some alarm.
