A tiny board which can turn your computer into an - Oscilloscope - Waveform generator - Logic analyser - Multimeter - and Power supply.
Great for makers or hobbyists with limited bench space or limited funds. Perfect for students and anyone starting out in the field of electronics
As you will see in the video below, I take a prototype of the EspoTek Labrador for a spin, and try out all of the functions that this board can provide.
I use an Arduino UNO, a couple of 433MHz RF modules, some LEDs and a speaker to see just how useful this board will be for my hobby requirements.
I have been wanting an Oscilloscope for quite some time, and while this board does not necessarily win against a benchtop oscilloscope on a side-by-side comparison of specifications, it does make up for it somewhat in terms of price, space (or footprint), usability, and wide range of functionality. But does it actually function as an oscilliscope? Is it useful ? Will it do what I need it to do? Or will I still need to buy that expensive oscilloscope that I have been saving up for?
Have a look at my review below, and tell me what you think.
Have you ever wondered if there was a way to store and retrieve data from a USB stick with an Arduino UNO? Most people choose SD cards to store their project data, but you may be surprised there IS a way! IC Station have a nice little module which allows you store and retrieve your Arduino (or other MCU) project data to a USB stick. I am not too sure why USB storage is not widely used in Arduino projects? These modules are not expensive, they have been around for quite a while, and are relatively simple to use. You do not need any libraries to get them to work, however, I must say that documentation for this module is not that easy to find. This site and this document proved to be very useful in my endevour to get this module working, and I hope my tutorial below will help you get started and bridge some of the information gaps. The...
Guest Post Disclaimer This is a guest post by the EasyEDA team. I would like to thank EasyEDA for providing this tutorial for everyone to enjoy. All information within this post was provided by EasyEDA. Description None of us could deny the fact that we would love with to play with LED’s and lighting stuff. I love to play with LED’s and create attractive lighting effects. This project was a result of such an attempt where I created a stunning RGB light effect using the popular development platform Arduino Nano. Let’s see the circuit, code and instruction on building this project: Parts Required: An EasyEDA account (free) Arduino Nano (or compatible board) LED strip Dupont wire connectors Custom control board Image source: EasyEDA Ardui...
FIVE MINUTE TUTORIAL Project Description: Sending Hex values to an Arduino UNO This simple tutorial will show you how to send Hexadecimal values from a computer to an Arduino Uno. The "Processing" programming language will be used to send the HEX values from the computer when a mouse button is pressed. The Arduino will use these values to adjust the brightness of an LED. Learning Objectives To Send Hexadecimal (Hex) values from a computer to the Arduino Trigger an action based on the press of a mouse button Learn to create a simple Computer to Arduino interface Use Arduino's PWM capabilities to adjust brightness of an LED Learn to use Arduino's analogWrite() function Create a simple LED circuit...
