3 Introduce Dontors Documenttion Kit V.4-8 Pge 3 The protocol commnds consist of only four chrcters, the lst chrcter is lwys "". The first symbol is the device type, the second symbol is the device identifier (number), the third symbol is the device sttus. A few exmples: the commnd to set the speed of the locomotive is equl to for plyer A hs the form "", switching of the junction D to the position stright "jd" An interesting point, there re lot of good mterils on the Internet bout the design on the bsis of Arduino. Much smller progrms for Android using Bluetooth for control. And, prt from simple exmples, there re prcticlly no posts how to tie together Android nd Arduino. The problem in the rules of dt trnsmission. For this purpose, number of good protocols hve been invented, for exmple the FIRMATA, which is included in the Arduino IDE collection of exmples, but it is for this project tht it is possible to mke the protocol simpler nd more flexible. In rilwy model, there is not lot of dt flow nd the speed of pssing the tem is lso not very importnt. Therefore, you cn use very simpliest URB protocol. And you cn chnge this protocol nd expnd it yourself. If you hve turntble on the lyout, then dding set of commnds strting with the "t" (Turntble) symbol, you cn control the riltble position in degrees multiple of ten "t34" (rotte the riltble to the position of 34 degrees). I will lso grdully dd new commnds to this protocol. This type of commnd is prsing by sketch, which is bsed on the exmple of Seril Event from Arduino IDE. For testing nd djusting your lyout devices you cn type these commnds directly into the terminl of Arduino IDE.

4 Dontors Documenttion Kit V.4-8 Pge 4 Why do you need it I think we lost control. Simple nd understndble mnipultions with the nlogue trnsformer hndle nd switches of junctions, when it is lwys cler wht hppens with your trins nd trcks, chnged to plurlity of digitl boxes in which mgic hppens. And this is very boring nd expensive mgic - it is incomprehensible nd constntly requires even more boxes. If you try to understnd DCC systems, it becomes very quickly cler tht this is very bd copy of industril digitl buses like CANbus nd others, nd the soſtwre is mixture of code written in vriety of objective progrmming lnguges, primrily Jv. I do not insist on my project, I just declre tht ll these digitl systems re too redundnt for modeller. I just tried to give you control over your hobbies. With the URB project, you only need to turn on the power your lyout, like old times. And not need computers :)
