I myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout. That is why I have written this ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

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 … ...

It intercepts the SPI calls from the Arduino to an SRAM chip, and translates the address information to find the appropriate data on a collection of 23K256 devices.

SPI is an interface, I dunno about the rest, but we do alot of work with SPI and I2C at work. If you got a pinout, you should be able to tell if they have the pins required for those interfaces ...

2) Display information to LCDs controlled by your Arduino. 3) Be programmed to act as an extensive combination lock 4) Offer commands, such as ENTER, LOAD, CLEAR, etc.
