Automatic Water Dispenser using Arduino

Automatic Water Dispenser using Arduino About 71% of earth is covered with water, but sadly only 2.5% of it is drinking water. With rise in population, pollution and climate change, it is expected that by as soon as 2025 we will experience perennial water shortages. At one hand there are already minor disputes among nations and states for sharing river water on the other hand we as humans waste a lot of dri ...

Simple Robotic Arm Project Using Arduino

Nowadays, manual labor is being reduced at big scale industries and factories to increase efficiency and gain profit by installing robots that can do repetitive works. A onetime installation of such a device may cost a huge amount, but in the long run, will turn out to be more profitable that manual labor. Out of the lot, a simple robotic arm is one of the most commonly installed machines. We are introducin ...

Water Level Indicator Using Arduino & Ultrasonic Sensor

Water Level Indicator Using Arduino Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. This project can be further enhanced to control the water level in the tank by turning it ON, when the water level is LOW, and turning it OFF when the ...

How to Build an Air Guitar With Arduino, Aka the AIRduino Guitar

The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at ChalmersUniversity (Sweden) for a Physical Computing class. The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to ...

NTP Clock

In this project, we will learn the basics of User Datagram Protocol (UDP). We will request and receive time from the NTP server using the above communication protocol. The 4Duino display is utilised to print the received time in both, digital and analogue clock format. Transfer of Data over Internet The 2 most common ways to transfer chunks of data (also known as packets) over the internet are Transmission ...

4Duino Servo Control

In this project, we will control the angular position of the DC Servo Motor via an I/O port (with PWM output capability) and touch knob. The 4Duino resistive touch display is used as a means for a graphical interface to control the angular positon of the Servo. Servo motor is a very useful device for hobbyists and robot enthusiasts as it allows your project to have moving parts. Servo motors are unique, as ...

Electronic Piano

In this project, we will learn how to use an Active Buzzer and a 4Duino to create an Electronic Piano. An active buzzer is an electric piezo device which is commonly used to produce sound. When subjected to an alternating electric field, a piezo ceramic material disc inside the buzzer is caused to stretch or compress, in accordance with the frequency of the signal thereby producing sound. Buzzers are widely ...

LED Matrix Controller

In this project, we will use the digital pins and screen of the 4Duino to create a 5×7 LED matrix controller with a user graphical interface. An LED matrix is essentially many LEDs packaged in a dot grid format in order to produce pictures or large text. They’re commonly used for signage purposes in the public space. The LED matrix utilised in this project is made by multiplexing 35 LEDs together such that ...

4Duino LED Brightness Control

In this project, we will learn how to control the brightness of LED via an I/O port (with PWM output capability) and a touch display slider. The 4Duino resistive touch display is used as a means for a graphical interface to control the intensity of the LED. Since the 4Duino itself has an LED on pin D13 with PWM output capability, you may use the LED to conduct this project for convenience. A LED (light emit ...

LED Control Using Touch Button

In this project, we will learn how to turn an LED ON or OFF via the 4Duino I/O port (D13) and a button widget from 4D Workshops. The 4Duino’s resistive touch display is used as a means for a graphical interface to control state of the LED. For convenience, we will use the LED on pin D13 of the 4Duino to conduct this project. An LED (light emitting diode) works on the basic principle that when potential diff ...
