Thermocouple Interfacing usng MAX31855 | Raspberry Pi

December 20th, 2016 No comments

thermocouple MAX31855Reading thermocouple data on Raspberry Pi using JAVA and Pi4J with the help of MAX31855 14 bit thermocouple to digital converter. The MAX31855 performs cold-junction compensation and digitizes the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples.

BLE

This video is all about sending and receiving data between BBC Microbit and any BLE enabled smart phone. Over here I have used C/C++ (MBED) as the programming language as other language (Python/JavaScript) don’t support UART data transfer service.

Fetching data from server | Arduino/ESP8266

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.

Programming using C/C++ (MBED Offline IDE Setup) | BBC Microbit

December 6th, 2016 No comments

mbed offlineThis tutorial is around BBC Microbit and programming the microbit using MBED offline C/C++ IDE but for this, I have used Yotta command line tool provided by MBED for building the code. This lets you explore many features of the microbit which otherwise are not accessible.
