Automatic Water Dispenser Project

Automatic Water Dispenser Project

It might not appear big at the first time, but if your tap dripped a drop of water once every second it would take only about five hours for you to waste one gallon of water, that is enough water for an average human to survive for two days. So what can be done to stop this? As always the answer, for this, lies with improvement in technology. If we replace all the manual taps with a smart one that opens and closes on its own automatically not only we can save water but also have a healthier lifestyle since we don’t have to operate the tap with our dirty hands. So in this project we will build a Automatic Water Dispenser using Arduino and a Solenoid valve that can automatically give you water when a glass is placed near it. Sounds cool right! So let’s build one…

DIY Arduino Motor Driver Shield

DIY Arduino Motor Driver Shield

In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling them.

Interfacing Flame Sensor with Arduino to Build a Fire Alarm System

In this article we interface Flame Sensor with Arduino and learn all the steps to build Fire Alarm System by using Arduino and flame sensor. Flame sensor module has photodiode to detect the light and op-amp to control the sensitivity. It is used to detect fire and provide HIGH signal upon the detection. Arduino reads the signal and provides alert by turning on buzzer and LED. Flame sensor used here is an IR based flame sensor.

What is Rotary Encoder and How to Use It with Arduino

A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of menu and Increasing/decreasing the value of a number and much more.

Alexa Voice Controlled LED using Raspberry Pi and ESP12

In previous tutorials we have seen How we can build an Amazon Echo Speaker and then how can we control any Raspberry Pi GPIO using Alexa Voice. Now we are making an IoT project to control home appliances from anywhere in the world using AlexaPi and ESP-12E (or any ESP board).

Arduino MKR1000 Wi-Fi Board

Ever since the launch of the ESP8266 module
which is a part of the Node MCU series, it has been increasingly used
in most of the IOT projects. The popularity of the device is due to its
cheap price and its ability to be programmed using Arduino IDE. Now
considering the price and functionality of an Arduino MKR100 Wi-Fi board, it is often confusing to select an ESP8266 over a MKR1000.

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.

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 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.
