Information Display System using WeMOS and MAX7219

May 12th, 2017 No comments

This tutorial is all about making a WiFi based information display system using WeMOS

This tutorial is all about making a WiFi based information display system. This system is built around ESP8266 but not the standalone ESP8266 instead WeMOS is used and programmed using Arduino IDE. So In this video, we will check out how to make an information display system like that using Wemos and MAX7219 based dot matrix display modules. The display system fetches data from the local/online server and displays the received. In this system, u can display any data that you want and that’s up to you however over here I am using this to display my YouTube subscribers and twitter followers count.

Onion Omega 2 Setup using Commandline

Omega2, the $5 IoT computer.It is a Linux computer designed specifically for building connected hardware applications. It combines the tiny form factor and power efficiency of the Arduino, with the power and flexibilities of the Raspberry Pi.

The Omega2 is simple, even for people who are just getting started with building hardware.The Omega2 is affordable, starting at just $5.
With the Omega2, we want to lower the barrier of entry and allow everyone to take the leap into hardware development.

Measure Distance using Ultrasonic Sensor HC – SR04 | Pi4J | JAVA | Raspberry Pi

January 16th, 2017 No comments

HC - SR04This is a simple tutorial showing how to interface HC – SR04  ultrasonic ranging module with Raspberry Pi to measure distance using JAVA. Ultrasonic ranging module HC – SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit. The basic principle of work:

(1) Using IO trigger for at least 10us high-level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning.

Fetching data from server | Arduino/ESP8266

December 9th, 2016 2 comments

Arduino/ESP8266Arduino/ESP8266: Fetching data to Server (LOCAL and Online) using WifiClient on from the ESP8266 module using Arduino IDE.

The chip first came to the attention of western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer, AI-Thinker. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. However, at the time there was almost no English-language documentation on the chip and the commands it accepted.The very low price and the fact that there were very few external components on the module which suggests that it could eventually be very inexpensive in volume, attracted many hackers to explore the module, chip, and the software on it, as well as to translate the Chinese documentation.
