Fig 1. An SPI-based output driver (in this case, an L9822 octal relay driver from STMicroelectronics) can be used to provide a random mix of I/O pins at the chip’s output. The circuit in (a) senses a ...

Industrial digital input chips provide serialized data by default. However, in systems that require real time, low latency, or higher speed, it may be preferable to provide level-translated, real-time ...

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

At The Conversation, we take table tennis very seriously. After setting up a new ping pong table, and wanting to learn how to use an Arduino, I had a bit of time to build a scoreboard. An Arduino is a ...

The MAX31915 translates and conditions the 24V digital output of sensors and switches used in industrial, process, and building automation to 5V CMOS-compatible signals required by microcontrollers.

Part of setting up a microcontroller when writing a piece of firmware usually involves configuring its connections to the outside world. You define a mapping of physical pins to intenral peripherals ...
