Getting started with Onion Omega 2 using Expansion dock and Web Interface

Onion Omega 2

Onion Omega 2, 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. Source: Onion Corp (bit.ly/2nTdC3U)

Control any load over Internet/ based on Temp. & Humidity | SONOFF TH10

SONOFF TH10

SONOFF TH10 /TH16 is a smart switch version of Sonoff which can monitor and set temperature and humidity through the iOS/Android APP eWeLink. Just as the name indicates, the Sonoff TH device supports two current supply specifications: 10A or 16A. It features presetting the range for temperature or humidity. When the temperature or humidity of the environment falls within the range, it will automatically turn on or off the connected devices. It supports three kinds of temperature and humidity sensors AM2301, DS18B20, DHT11 Source: bit.ly/2lCttDp (ITEAD)

BMP180 Interfacing with Arduino | In Depth

BMP180 with Raduino

This video is all about interfacing BMP180 module with Arduino. BMP180 will help us to measure environmental temperature and pressure and by using that we can calculate the altitude which can be used in various applications like weather monitoring, navigation etc. The BMP180 sensor module comes with the I2C interface and with a default address 0x77 which is not configurable limiting stacking of multiple modules to that same I2C bus. In this tutorial, we will interface the module with Arduino by using I2C interface that is analog input pin A4…

IIC (I2C) Communication on Raspberry Pi by using JAVA

MCP23017 with raspberry Pi using I2C Communication

This tutorial is all about IIC (I2C) communication on Raspberry Pi by using JAVA and for that, I have used Pi4J library. To demonstrate this in the tutorial I have used MCP23017 Port expander IC with Raspberry Pi. MCp23017 is a 16 Bit input/output Port Expander ICcomes with I2C Interface. To interact with the IC suing IIC (I2C) port  here we have used Pi4J and JAVA. MCP23017 Features: 16-bit input/output port expander with interrupt output Cascadable for up to 8 devices on one bus 25mA sink/source capability per I/O Supports 100kHz, 400kHz,…

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

uLTRASONI pI

This 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…

Fetching data from server | Arduino/ESP8266

Arduino on ESP8266

Arduino/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…
