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 ...

Mini Arduino Lux Meter

I needed a Lux meter for testing flashlights. There are some good lux meters available in the $15-25 range, but shipping always takes a long time and I needed it now. That's when I realized that I had an unused BH1750 light meter module laying around, which I bought some time ago but never used it. So I grabbed an Arduino, a Nokia 5110 LCD, wired everything up on a breadboard and had a functioning lux meter ...

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 ...

Control ESP8266 over the internet

There are but a few things better than (succesfully) programming and using your Arduino. Surely one of those things is using your ESP8266 as an Arduino with WiFi! In this instructable I will show you an EASY way to get the ESP8266 working as a web server AND accessing that server from anywhere (over the internet) Also if you find this instructable interesting, perhaps you'll like some of my others: EASY Ard ...

Amazon Dash Button for Arduino!

A project using the AmazonDRS library for WiFi101 connected Arduinos. Just like the AWS IoT button, but completely open source! Things used in this project Story TL;DR; Buy some stuff on Amazon by clicking a pushbutton connected to your WiFi101 enabled Arduino. It's like a Dash button, but cooler! Motivation Back in the Spring of 2015 Amazon released the Dash Button to help facilitate frictionless product p ...

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 ...

ESP8266 + I2S = Software-based 10-Base-T Ethernet Driver

espthernet It's pronounced "e-s-peethernet" - a party trick, not a legitimate engineering solution. ESP8266 + I2S = Software-based 10-Base-T Ethernet Driver For a detailed overview of how this project works, please see the Hackaday article. For a rough idea of what's going on, checkout the youtube video: Overall Discussion This is a relatively unreliable and coincidentally functional ESP8266 Ethernet driver ...

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 ...

Control a Cockroach with Arduino for under $30

Ever wanted to control a cockroach on the cheap? Now you can! Things used in this project Story A few years ago I saw Backyard Brains' smartphone controlled cockroach, and it just blew my mind! I tried to get my mom to let me buy it, but the mention of cockroaches convinced her otherwise. :) I started doing projects with the Arduino a few years later. I remembered how much I wanted to do the cockroach exper ...

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 ...
