IoT integrates the knowledge of electronics with sysadmin works. Day by day, the cost of bandwidth decreasing. Most of us with postpaid plans from ISPs have unused bandwidth left in hand. We will discuss different IoT cloud platforms for the makers and developers which can be used to test things made with Arduino, NodeMCU, Raspberry Pi. Although things made in China readily available, DIY things … [Read more...]

Getting Started With IBM Cloud IoT (Watson IoT Platform)
IBM Cloud IoT is free for ordinary usage. Here is a How To Getting Started With IBM Cloud IoT. We want to provide the basic idea of what Watson IoT Platform does and what to expect from it. On November 2018, IBM rolled out this newer version of "Watson IoT Platform" with much more features. Commonly we need these cloud-based IoT platforms for Arduino based devices (like, ESP32 we discussed this … [Read more...]
ESP WROOM 32 : How To Setup ESP32 NodeMCU With Arduino IDE
Here is Step by Step Guide to Setup on How to Setup ESP32 NodeMCU with Arduino IDE on Windows 10 PC. In our previous article, we recomanded ESP WROOM 32 dev board over Adafruit Feather as cost effective option. In this guide, we will help to setup ESP WROOM 32 dev board with Arduino IDE. We are using clone of DOIT ESP-WROOM-32 Devkit V1 and for the most boards, these are "ESP32 Dev Module" to … [Read more...]
Arduino, NodeMCU ECG : AD8232 Single Lead ECG Module
Single lead means it has 3 connecting leads. The traditional ECG machines have 6 leads. Computerized ECGs have 12 leads. Patient monitors inside OT/OR often have one lead. The Arduino based patient monitor board we discussed before is costly and actually never became hugely popular. The module can extract, amplify, and filter small biopotential signals. ECG is the recording of the electrical … [Read more...]
WiFi With Arduino For IoT : ESP8266, ESP32, NodeMCU, Adafruit Feather
This is not-so-formal article to introduce to ESP32, NodeMCU, Adafruit Feather to the users who are not that much used with the boards. ESP8266 has wider range of models and ESP 01 commonly seen as cheapest. Writing few guides on ESP8266 (ESP 01) is for normal for any technical website but in real life, using ESP 01 not easy. It is backdated, not exactly designed to be used with Arduino board as … [Read more...]
Wearables and Internet of Things : Part II
In the previous part of this series on Wearables and Internet of Things, we briefly discussed about the wearables. In this part, we will discuss the basics on Internet of Things and the communication protocols used in conjuction of current wearable technology. Historically wearables were simple mechanical calculators. But right now, wearables means some sort of electronics using communication … [Read more...]
LED Bar Graph Progress Test : Arduino & Transistors
Previously, we have discussed about LED Bar Display. If you do not have LED Bar Display, you can use common LEDs for testing purpose. Here is Circuit and Code to Create LED Bar Graph Progress Test Project. We Will Shown the Project With Arduino and Als Only With Components Like Transistors. Basic matter of this project is that - we are using a potentiometer as analog input. When we rotate the knob … [Read more...]
5 Tips to Fully Leverage the Reach of SMS Marketing for Businesses
SMS is not outdated as many of the newcomer digital marketers think of it. However, not all text marketing campaigns are not the same. Some marketers use it as a standalone marketing strategy whereas some others integrate it into their business marketing strategy. According to a survey conducted by a leading mobile market research agency, about 89% of the mobile phone users tend to access SMS … [Read more...]
Difference Between Object Storage and Block Storage
Users commonly seek the difference between Object Storage and Block Storage. We have good number of publications on this website on object storage to point towards the differences, but often that process was as a part of answering some other question, such as Methods of Encryption in Cloud Object Storage. Object Storage is newer technology. Object storage has a flat structure where files are … [Read more...]
Methods of Encryption in Cloud Object Storage : OpenStack & IBM Cloud
Users can encrypt each object on cloud storage using the provider's way, such as using private and public keys. Throughout various articles on this site we discussed about cloud storage and security methods. We often talk around data encryption on cloud storage but avoid going in-depth. Object Storage is a data storage architecture which manages data as objects. Each object typically includes the … [Read more...]
