Launched in 1996, the AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two ...

Here’s an interesting article about reading data from shift registers using less than three pins. 74HC165 shift registers are a popular choice for adding inputs to a microcontroller. They have a ...

A Microcontroller uses many different protocols to communicate with various sensors and modules. There are many different types of communication protocols for wireless and wired communication, and the ...

After a time with a multimeter and scope, the othewise-undocumented Cronos board for home-build cnc machines has revealed some of its secrets. Overall, it seems like a proper grown-up design with a ...

At this stage I am presenting a concept rather than a project ready to be built. In a nutshell, the concept is a rethink of the board stacking arrangement used in microcontroller systems such as ...

In most keypads, pressing a key closes a contact that bridges two lines in an xy matrix. If you use a microcontroller to detect a key closure, checking the states of (x+y) lines requires an equal ...
