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 ...

Getting Started with Micro Python

In a previous blog, Using MicroPython for real-time software development, I examined the idea behind using MicroPython for real-time embedded software. Now, let’s examine some of the core pieces that developers need to understand to get started using MicroPython. The first step a developer interested in MicroPython must take before diving into a real-time embedded application is to select a supported develo ...

Obstacle Detection

In this project, we will use several ultrasonic sensors to create a robot car with obstacle detection feature. The sensors will help us estimate the distance of the car from the nearby obstacles. Thus allowing us to create routines that we can execute when the car is about to hit the obstacle while moving. If you want to know more on how an ultrasonic sensor work, please refer to 4Duino Ultrasonic Sensor pr ...

GPIO Control from Web Browser featuring 4Duino-24

In this project, we will learn how to control the on board 4Duino LED via I/O port (D13) from web browser. In built ESP8266 Wi-Fi module is configured as server enabling the 4Duino to receive commands from a web browser (client). How it works Note: This project could be carried out only if the Client and the Server are in the same network because your home router prevents the 4Duino server to be accessed fr ...

Arduino Voltmeter With OLED Display

Hello ! I'm going to show you how to make a voltmeter* with Arduino UNO, an OLED display, 2 resistors and 9 jumpers for less than 5 minutes. With it you will be able to measure Voltage from 0 to 50V (if you exceed it you may damage your Arduino !). Lets begin ! *"A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit" - Wikipedia Step 1: Par ...

Pet Food Dispenser featuring 4Duino-24

In this project, we will use a 4Duino and several IR sensors to create a simple pet food dispenser. 4Duino checks whether a food tray contains enough food or not. It is programmed to read IR values from each sensor. These values change depending on the amount of food in the container.  The feeding time can be set by the user via the graphical user interface. The device continuously checks the time from an N ...
