Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate project, one that has been on the back ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

The Raspberry Pi Pico board's pinout tells us that there are 2 x SPI, 2 x I2C and 2 x UART. These all work fine as far as my tests have confirmed. Please could we get the pins_arduino.h file updated ...

Components required to build a digital meter are simple and can be easily found in your local store; the complete list of components is given below. The complete schematic diagram of the Arduino ...

There are two kinds of people in the world (and, no, this isn’t a binary joke). People who love the Arduino, and people who hate it. If you’ve ever tried to use a standard prototype board to mount on ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...
