Raspberry Pi GPIO Explained. Part 1

The Raspberry Pi is a computer, and from a connections point of view it doesn’t look much different to a normal desktop computer. It has USB ports for connecting a keyboard and mouse, and a video output port for connecting up a display. Because it is more compact and lower cost than a large desktop PC, it becomes possible to use the Raspberry Pi or other small single board computers as they are known, for many scenarios where a desktop or laptop PC would not be feasible...

STMicroelectronics is extending choice and freedom for budget-conscious designers by introducing its new 8-bit STM8S001 microcontroller in the economical SO-8 package. Unlike most rivals, the STM8S001 has I2C, UART, and SPI interfaces, giving unusually versatile connectivity options...

Holtek new BH66F2650 2660 Flash MCUs
Holtek new BH66F2650/2660 Flash MCUs for eight-electrode AC Body Fat Scale Applications

Following the successful previous release of its four-electrode AC body fat scale, HT45F75/77 devices, Holtek is now delighted to announce the release of its new eight-electrode AC body fat scale Flash MCUs, the BH66F2650/60. Eight-electrode body fat scales are used to measure body fat including legs, arms and torsos measurements which can reflect the body condition...

Microcontroller Battery Monitor Circuit Needs Only
Microcontroller Battery Monitor Circuit Needs Only One Pin

A microcontroller's internal ADC was inadequate to measure its own supply rail, so a circuit using standard discrete components was devised to do this with just one pin of the IC. This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries...

Controller for automatic lighting of the working area in the kitchen. Part 2 - NodeMCU Version. Schematic, PCB, Sketch

The second version of the controller is made on a popular  Wi-Fi module such as NodeMCU, which is based on the powerful Espressif ESP8266 system-on-chip. Such a solution will allow us to implement in our light controller additional functions inherent in the devices of the Internet of things...

One wire controls LCD module
One wire controls LCD module

The ubiquitous LCD (and VFD) modules based on the HD44780 controller IC can require up to 12 lines from the host. This hardware interface Design Idea  reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard interface, or even an opto-isolator...
