BMP180 Interfacing with Arduino | In Depth

February 10th, 2017 No comments

BMP180This 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 and A5. And for this, we are not going to use any library although if you are interested you can use any library available online which are actually pretty easy to use. Interfacing the module without any library will help us learn how it works as well as we can interface to other devices also where libraries are not available.

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.

Getting started with ESP8266 | AT Commands

September 26th, 2016 No comments

Connecting the ESP8266 Wi-Fi module to PC and trying out some AT Commands.The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems.

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.

The ESP8285 is an ESP8266 with 1 MB of built-in flash, allowing for single-chip devices capable of connecting to Wi-Fi.

Getting Started with Smallest Arduino | Digispark AtTiny85

September 22nd, 2016 No comments

The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much.

Specs:
Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
Power via USB or External Source – 5v or 7-35v (12v or less recommended, automatic selection)
On-board 500ma 5V Regulator
Built-in USB
6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all                                    6 even if you are programming via USB)
8k Flash Memory (about 6k after bootloader)
I2C and SPI (vis USI)
PWM on 3 pins (more possible with Software PWM)
ADC on 4 pins
Power LED and Test/Status LED

In this video you will find a detailed description of the smallest Arduino compatible board like how to configure your Arduino IDE in order to program this board.
