Interfacing thermocouple with Raspberry Pi using MAX31855

Bikash Narayan Panda

Reading 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. Check here for more details. …

Send/Receive data using BLE and MBED | BBC Microbit

BLE Microbit

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 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…

Custom Character Generator for 16×2/Dot Matrix LCD

Bikash Narayan Panda
MAX7219 LED Matrix Custom Char

Around microcontrollers, 16×2 LCD is a great way of displaying information to users. They are the cheapest and easy to use. Moreover, there are tons of libraries available to use these across different microcontrollers. If you want to learn more about 16×2 displays interfacing, you can check out this post. In this post, we will discuss how to show custom characters in a 16×2 LCD and dot matrix displays also. To generate the array bytes for such character generation I have written a small JAVA program, which lets you draw…

2N7000 logic level shifter

The 2N7000 and BS170 are N-channel, enhancement-mode MOSFETs used for low-power switching applications. The two are nearly identical except that the leads are arranged differently and the current ratings are somewhat different; they are sometimes listed together on the same datasheet, along with other variants 2N7002, VQ1000J, and VQ1000P.The 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use, along with such other popular discrete semiconductors as the 1N4148 and 1N4001 diodes; the 2N2222, 2N3904, and 2N3906 bipolar junction…
