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.

Raspberry Pi Twitter Bot

Raspberry Pi Twitter Bot

Today’s Tutorial relies heavily on the python library, Twython, which is a python module for interfacing with twitter. With twython, we could do most of the things you normally would want to do on your twitter handle like send DMs, Post tweets, read tweets, read DMs, Upload an image, change DP, Change background image, and a lot more. Twython requires authentication from twitter, which can be received by creating a twitter app.

LED Binary Clock using Arduino

In this LED Binary Clock Circuit, we have used Arduino Nano to control the whole project like reading time from RTC and showing that on LEDs. A 3.0v coin cell is connected to RTC IC for backup.

Remote Controlled Car Using Raspberry Pi and Bluetooth

Today we going to build a Remote Controlled Car using Raspberry Pi 3 and Bluetooth, here we will use Smart Phone as a remote to control the car.

Here we are using Raspberry Pi 3 which have inbuilt Bluetooth, so we don’t need to use any external USB Bluetooth dongle. Here we are using RFCOMM Bluetooth protocol for wireless communication.

Simple Two Way Intercom Circuit

In this tutorial we are going to build a very Simple Intercom Circuit using which you can communicate two ways locally within your house or school. This project brings in the childhood memory of using matchboxes with thread to build a simple telephone. So now let’s take it to the next level by building an electronic circuit (amplifier) to transmit voice from one end to another end.

Arduino Calculator using 4×4 Keypad

In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could perform simple operations like Addition, Subtraction, Multiplication and Division with whole numbers. But once you understand the concept you can implement even scientific functions with Arduino’s built in functions
