What is IoT? Different IoT platforms with a free option

We hear about the Internet of Things (IoT) for quite some time. I think it is safe to say that IoT started with the first internet message sent on 29 October 1969 over ARPANET. It appears that Kevin Ashton first pronounced the term of Internet of Things in 1999. I could be wrong, but I’m fairly sure the phrase “Internet of Things” started life as the title of a presentation I made at Procter & Gamble (P&G) in 1999. Linking the new idea of RFID in P&G’s supply chain to the then-red-hot topic of the Internet was more than just a good way to get executive attention. It summed up a valuable insight, which is still often misunderstood. Kevin Ashton

Cloom Published a “USB Cable – Everything You Need To Know”

https://www.wiringo.com/usb-cable-everything-you-need-to-know.html Cloom, a reliable wire harness, and cable assemblies manufacturer, today published a “USB Cable – Everything You Need To Know.” It has five chapters that cover some useful terms about USB Cables knowledge. The publication is available here for free. This guide sheds insightful light on these USB cable properties. “The Cloom R&D team adapts quickly to the changing market needs. The R&D team helps customers in developing the design, advising on the material, developing new products, and ensuring that the essential requirements for ROHS, REACH and halogen-free for wiring harnesses are met,” said Mr. Hommer, General manager of Cloom. Among the key subjects on this USB Cables include: What Is USB：This section briefly introduces the definition and features of USB cables. Types Of USB Cable: This section introduces various types of USB cables in depth and theirs application.

How to Make Your Home Network Inaccessible to Criminals

With hacking, virus propagation and other forms of cybercrime on the rise, it behooves every security-conscious individual to take measures against these threats. This is where the adage “Security starts at home” comes into play. If cybercriminals are able to find their way into your home network, the consequences could be disastrous. In addition to having various passwords and logins stolen, members of your household could have their most sensitive online information compromised. To ensure this never comes to pass, you’ll need to beef up security around your home network. As you’ll find, stepping up network security doesn’t have to be costly, difficult or time-consuming.

FreeRTOS tutorial on STM32

A High-density line of STM32 microcontrollers has quite a bunch of features that can be used in your programs. However, the more features you add to the source, the more complicated the program becomes, and it may become challenging to keep up with all things. Relying on the main loop and interrupts becomes a time-consuming task to manage. If you do not want to struggle while tuning things up manually, you can use one of the best free real-time operating systems (RTOS). It is handy when you need many separate functions to run in parallel without missing a task. RTOS scheduler takes care of giving each task a required period to perform. There are many great RTOS systems around. Many of them are free and open source. Follow the FreeRTOS tutorial to see how easy it is to run complex tasks. I love using FreeRTOS, which has a long successful history and is flexible to fit multiple types of hardware. You can check out my demo FreeRTOS tutorial on Atmega128. I also encourage you to give a try for other RTOS systems like ChibiOS, BeRTOS, and others. FreeRTOS is quite simple and easy to use. It has practically all of…

Flashing programs to STM32. Embedded Bootloader

Post updated with new screens and up-to-date information (2019)! There have been several requests from users to explain more about loading programs into the flash memory of STM32 microcontrollers. There are several ways on how to perform stm32 flash programming. You may enter the STM32 bootloader directly via USART interface and upload the binaries. The more advanced and flexible method is to use an ST-LINK utility – an ST-based adapter, which connects to STM32 board through JTAG interface. Many ST development boards already have this feature included. Otherwise, you can jump-wires from one to another, or get a dedicated portable ST-Link adapter. Also, you can use standard third-party JTAG tools such as J-Link. Finally, you can flash your bootloader that works with any interface (USART, USB, SPI, etc.) The STM32F103RB board Any of these methods are great if they get the job done. In this topic, let us focus on how to perform STM32 flashing by using a bootloader. Today probably, no manufacturer is producing developing boards with RS232 interface. Nevertheless, you like me, probably have a dozen older boards with a serial port. They are great boards still to use in many projects.

Effects of Thermal Conductivity on Soil

Thermal conductivity is the ability of soil to conduct heat, and thermo-mechanical analyzer is used to check the thermal conductivity of the soil. Thermal conductivity measurement proves helpful to judge the temperature of the ground in the fall, to have an idea of its temperature in a different season like summer or winter. You can buy special meters to check the thermal conductivity of the soil. If you want to design meters, check mjsdesigns.com to buy latest boards and chips. It plays a vital role to know about different aspects of microenvironment like vegetation, eating habits of animals, and microorganisms in the soil. Thermal conductivity is specifically crucial for agriculture to check the nature of the soil. It is essential to understand the properties of geothermal energy sources and to check the transferability of heat from one area at a given temperature incline. Seed Germination and Emergence Different types of seeds are used to grow different plants, but the time of development for each plant is based on the temperature of the soil. Thermal conductivity of soil effectively transfers the heat of the sun into the ground, and this transfer rate will determine the developmental process of seed. Prefer soil…
