A common problem that often comes up when working with micro controllers, is running out of IO for all the input the projects requires. So I came up with this solution that allows a user to have up to 4096 button inputs using only 4 lines of IO. This is done by sending out data

Rigol has shown a new range of oscilloscopes and signal generators at the Electronica 2018 tradeshow last week. Report by Nick Flaherty @ mwee.com The MSO/DS7000 mixed-signal digital oscilloscope series is based on On-chip ASIC technology from Rigol and provides bandwidths from 100 MHz to 500 MHz and sampling rates of up to 10 GS/s for research, development and production.

The display demand for every project is unique, a project may require just a simple, single character OLED display, while another project may require something bigger, all based on the function the display is to perform. For this reason, as a maker or electronics hobbyist, anyone needs to know how to work with as many

Oscilloscopes are an essential tool for electronics hobbyists and professionals to verify that their designs would work as expected. PC-based oscilloscopes score over standalone oscilloscopes due to their compact size, low cost and ability to do offline analysis. Here we describe how you can make your own oscilloscope at a very low cost using your

Arduino Based Real-Time Oscilloscope The Oscilloscope is an essential instrument for the workbench of every electronics engineer or maker. It is primarily used for monitoring waveforms and analyzing voltage levels, frequency, noise, and other signal characteristics that can change over time at its input. Embedded software developers utilize it for code debugging while technicians depend

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it

I am a Physicist and the nicest part of working in this field is that I get to build my own instruments. With this way of thinking, I decided to build a homebrew Arduino Oscilloscope. This instructable was written with the purpose of teaching a bit about microcontrollers and data acquisition. This is an extreme
Girino – Fast Arduino Oscilloscope using Arduino power connector Continue Reading
This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used to measue time-varying signals. Any time you have a signal that varies with time(
One of the frustrating things about developing and debugging electronic circuits is that you can’t look inside the circuit to see what is happening. Even with a circuit laid out before you on a workbench and powered up it may seem like you’re in the dark, unable to figure out why an input change or
