A short video showing how to extend a simple circuit out from the Arduino.
Here’s a source for breadboards on Amazon: http://Amazon: http://amzn.to/2CHpeLK
You can get a set of 3 Arduino Nanos here: http://amzn.to/2mbrbsG . You can’t beat the price of these Chinese clones, but know that you will need to solder the headers on, and you may need to download a driver for these Chinese clone boards. See how I do that in my video here: http://mechatronicsworkshop.com/index.php/2017/12/14/arduino-nano-prep/
You can purchase clones with the headers already soldered on if you search for them. Be careful buying clones — these appear to come from a warehouse in the U.S. so shipping is quite fast to the U.S. But be careful that you don’t buy them from a supplier who ships from China unless you or ok waiting for three to four weeks to get them delivered.
If you want to pay more and have the headers soldered on and no need to download a driver, go to the Arduino.cc site and purchase the original boards there.
Elenco is a great company to find larger breadboards, and all sorts of fun electronic stuff: http://amzn.to/2maSIun
