This is a bit off topic but I couldn’t find this piece of information anywhere on the Internet and managed to find out myself. So it’s probably better to share.

In this project we’ll build a small device that measures the distance of an object in front of it and displays the result in centimeters. We are going to combine three gadgets:
- HC-SR04 sensor for measuring the distance
- Arduino Nano clone for communication between the modules and doing some calculations
- A small OLED screen for displaying the result
When you need to read some kind of output from a DIY electronic device and a notebook is out of reach a small display might be the solution. In this post I’m writing about an inexpensive 128×64 pixel monochrome OLED display. Let’s get started!

Today’s subject is a very popular sensor module for small autonomous robots. Why is it so popular? Because it is extremely cheap, easy to use and quite reliable. Let’s see how to hook up the module with an Arduino. Read More
I remember the first GPS unit I bought was a USB device with a sirf3 chip (20 channels, 1 Hz) and it costed around $45. Now I can buy an Ublox NEO-6M under $20 and get much more (50 channels, 5 Hz and other good stuff). Read More
If you need a breadboard-friendy, well documented and supported Arduino board, your best choice is a Nano. Unfortunately an original Arduino Nano could cost you around $30 plus shipping so it makes sense to search for an alternative source. There are also some chinese clones that are around five times cheaper, even with worldwide shipping.
But wait! There’s always a reason why a clone of something is cheaper than the original product. In this case there can be two pitfalls you need to know about.
