Two weekes have already passed since I ordered a Spark Core to Maker Shed. It has not delivered yet. Because I cannot wait I sent the another order for Getting Started Kit with Arduino to Amzaon.
The Spark Core uses Arduino programming language so it will be good for me to learn Arduino beforehand.
As a companion to stduy I also ordered Getting Started with Arduino, 2nd Edition. I can’t wait until I get the package!
