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 ...

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

// SPI (Not pinned out) #define PIN_SPI1_MISO (31u) #define PIN_SPI1_MOSI (31u) #define PIN_SPI1_SCK (31u) #define PIN_SPI1_SS (31u) #define SPI_HOWMANY (0u) But for accesing the onboard SD-Card - I ...

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 ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...

Every week the Hackaday tip line receives an email about a new dev board. The current trend is towards ARM devices, and only once have we seen an x86-based device. Today that count went up to two.

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 ...

The planet Mars has captivated our imagination for centuries, and the idea of sending rovers to explore its surface has fueled our curiosity even further. In this project, we will delve into the ...

Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for ...
