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 ...

SOMO-II MP3 Player

The Sound Module-II or the SOMO-II is a small and efficient audio module from 4D Systems that is able to play .mp3 or .wma audio files in the convenience of accessing it within a microSD card or a USB Flash drive (by using external components). The aim of this project is to showcase the basic functions of the SOMO-II Audio Module such as the Play, Pause/Stop, Next, Previous and the Volume controls. The equa ...

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 ...

DC Motor featuring 4Duino-24

In this project, we will learn how to control the speed and direction of a DC motor via I/O ports with PWM output capability, a L293D quad half-h drivers IC and 4D Workshop widgets. In its simplest form, a DC motor has two wires which is connected to a power supply. Depend on whichever way current flows in the DC motor, this will determine the direction in which the motor will spin. Motors are often used in ...

DJ Mixer featuring 4Duino-24

The 4Duino DJ Mixer is a fun and interactive project similar to a keyboard MIDI Controller that has the ability to play sample beats and songs. Before, DJ and music artist needs to use computers, recording and playback devices before they can mix and play their own customized music. But using this project, the user can utilize the 4Duino LCD screens and the 4D SOMO-II music module. The 4Duino will serve as ...

WiFi Temperature Sensor featuring 4Duino-24

In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time. How it works Components 4Duino TMP 35 Temperature sensor Bread Board Jumper cables µ ...

Home Security featuring 4Duino-24

Home Security project is a password oriented security device. This uses 4Duino display as the user interface where the password can be entered. 4Duino is also used as the host device in this project. It handles a buzzer, an ultrasonic sensor, a uCAM-II and a magnetic switch. As a home security device, it sends an alarm to the owner when there is an attempted entrance or any malicious kind of entrance. Initi ...

Controlling RGB LED using Arduino and Wi-Fi

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we have used an Android Mobile App named “Blynk”. Blynk is a very compatible app with Arduino, ...
