DIY an Arduino Nano-Based Oscilloscope

• Tweet
• Pin It

Maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors.

The simplest version of this device, which he calls the ArdOsc, displays data on a computer screen, but a 1.3” OLED can also be added if you want to use it on its own.

This little oscilloscope can be modified adding capabilities including a logic display, signal generator, and other useful tools according to the needs.

ArdOsc specifications include:

• max 1M samples/second, min 1000sps
• 8-bits per sample
• DC 0-5V; AC +/- 550mV, AC +/- 117mV, AC +/- 25mV
• USB “PC scope” or built-in display
• could be battery-powered
• optional logic display
• optional frequency meter
• optional voltmeter
