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
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.
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.
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.
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.
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
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.
