An Arduino is by no means expensive, but that still doesn't mean that it suits your needs right out of the box. If you want to make your own custom board, Make shows you how in a three-part series.

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

On top of the board's simplicity, there are several more reasons why it's highly recommended for beginners. First, it's conveniently included in popular starter kits like the Arduino official ...

Arduino no longer produces this board. Unfortunately, the more popular boards like the Uno, classic Nano, and Mega 2560 don't support the Debugger feature as they're powered by an AVR microcontroller.

The Arduino Zero uses an Atmel ARM Cortex-M0+ for 256kB of Flash and 32k of RAM. The board supports Atmel’s Embedded Debugger, finally giving the smaller Arduino boards debugging support.

To make your own Arduino based oscilloscope, follow these four steps. Your board will be able to use up to four input channels at frequencies up to 7 kHz and as many as seven input channels at 4 kHz.
