As you can see, the connections on J2 are nice and simple.
Pin Note RX Connect this to TX on your serial port.
555 timer experimenter kit - 555exp Introduction The 555exp kit allows you to easily experiment with both the monostable and astable modes of the classic 555 timer IC. The kit uses only through-hole components making it suitable for anyone to construct.

Build Instructions Kit contents The kit contains the following:
1 * 555exp PCB 1 * 555 timer IC (with socket) 2 * 470uF electrolytic capacitors 1 * 10nF ceramic capacitor 2 * 5mm red L.
Introduction The CopyMe84A1 kit allows you to build a clone of the classic “Simon Says” electronic game. I’ve tried to keep the build as simple as possible in order to make this kit suitable for beginners.
This kit is fully open source, both software and hardware. Please visit its github page for access to the source code and Kicad files for the HW.
You can buy a complete kit of parts from our store.
For various products in our store, we wanted a way to be able to associated a shortish name with the full url to its entry in our store or blog. As Go seems to be gaining traction as the go-to language for writing web services we decided to write yaurls in Go. This is our 1st proper application written in Go, but based on this, I don’t expect it to be our last.
Introduction The Arduino IDE is a great bit of software to get you up and running quickly, but as projects get larger, or if you already have preferred code editor etc., it might not be the best way to go. In this post, we will discuss a simple approach to building projects for Arduino with-out using the IDE. The Arduino IDE still needs to be installed, we need some of the libraries it provides, but we won’t actually need to run it to develop code for the Arduino platform.
Introduction Some basic instructions on how get yourself setup to build C/C++ programs for Atmel’s AVR micro-controllers.
The will install the following versions:
GNU Binutils version 2.26 GNU GCC for AVR version 5.2.0 AVR libC version 2.0.0 Before you start, you need to decide where you would like to install the tool-chain. The default is something like /usr/local which will require root access. If don’t have this, or prefer to install in a non-system location you will need to configure the build system as such.
After months of nagging, I recently upgraded my Windows 7 box to Windows 10. Initially all was good, that was until I needed to access my DVD drive. For reasons known only to Windows, my DVD drive had disappeared. After much searching the far corners of the internet, I found the answer to my issue. Hopefully it will work for you, but please take care when performing these steps otherwie you could make things worse…
