{ "item_title" : "Arduino Model Railroad Signals", "item_author" : [" David Jay Bradt", "Joanna Opaskar", "Paul David Bradt "], "item_description" : "This book provides very basic ideas for the model railroad enthusiast to develop automated signal projects. Most of these projects are HO scale, however there is one G scale semaphore signal. It also provides the basics on using and programming the Arduino micro-controller. These projects are great starting points for projects that specifically fit the model railroader's own system. If interested in more advanced projects please see our Arduino Intermediate Model Railroad projects.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/51/684/712/1516847121_b.jpg", "price_data" : { "retail_price" : "23.49", "online_price" : "23.49", "our_price" : "23.49", "club_price" : "23.49", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
