ARDUINO ANTENNA ROTATOR PART1 - SOFTWARE AND PROTOTYPING 

Hello Cerdano. It’s the standard Adafruit library. I am not at home right now. I’ll be back in a couple of days and i’ll give you more details.

Hi Hugo, It's possible, with small changes in the code. The AR-500 is good and rugged, but has a major disadvantage, it doesn't have a feedback, a means to know precisely where the antenna is pointing. Usually this is done with a potentiometer geared to the shaft. If you want to use this rotor with computer control, you have two options: 1. Use your mechanical skills to install a potentiometer inside, and have a very precise positioning. Everything is great, and you can use any tracking software you want. 2. Leave it as it is, and the software will rely on timing to calculate the antenna position. Assume the rotor does a full rotation in 2 minutes, this means 3 degrees per second. So we power the rotor for a certain amount of time, to go from one position to another. Less precise, and require re-calibration from time to time. PstRotator is the only software I know which is capable to do this. Send me an email if you want to go further.

Hello, Sorry, I can't help you with stepper motors. If you really want to use steppers, check the control module for Arduino: www.aliexpress.com/item/1005001621676770.html?af=2049356_1&cv=41155805&cn=45rc2gyxk250l4uzx98uobqm5enp5lr4&dp=v5_45rc2gyxk250l4uzx98uobqm5enp5lr4&af=2049356_1&cv=41155805&cn=45rc2gyxk250l4uzx98uobqm5enp5lr4&dp=v5_45rc2gyxk250l4uzx98uobqm5enp5lr4&product_id=1005001621676770&afref=&aff_fcid=ceaa0a6340334d2386f18e5d8eacfc37-1652857450091-08966-_9G57Xi&aff_fsk=_9G57Xi&aff_platform=portals-hotproduct&sk=_9G57Xi&aff_trace_key=ceaa0a6340334d2386f18e5d8eacfc37-1652857450091-08966-_9G57Xi&terminal_id=4972137dadb64dd9a06e8dba10bc46cb&afSmartRedirect=y This can be easily interfaced with my code, but the motor will have a fix speed, no speed control. Not a great solution.

Salut Cristian. Multumesc. Motoarele sunt in lucru si vor fi publicate curand. Intr-adevar, sper sa fie imun la emisie, fiindca are doar potentiometrele de pozitie langa antena si carcasa metalica. Anunta-ma cum merge.

Hey Nicola. Sure. Send me an email and let me know what you need.

Hi Bonchart, There is a link in the description towards a plugin for Orbitron, which sends the coordinates to USB. After installing and launching this plugin, select the port where your arduino is connected and then select Custom Format and input the following text: AZ[AZ] EL[EL] This way, the plugin outputs a message like AZ25.5 EL45.7 which the Arduino takes in and translates into antenna movement.

@@Racov Thank you very much, i will try to do it :)

Hello Mattia. I use 1 kiloohm. Any value between 500 ohms and 1 ko will work fine.

Please do Yo3rak at gmail.com

No. The code is written by me. I know about K3NG controller, but at the time, I couldn't find any complete information about his project. So I did my own 😁

Salut Andrei. Acesta este un controller pentru un rotor de antena. In domeniul radio-amatorilor, se pot face legaturi radio prin satelit, si atunci e nevoie sa orientezi antenele pe satelitul respectiv, iar acestea se misca pentru a urmari orbita satelitului. Comanda pentru pozitionarea antenelor e data de un program de calculator, care stie in permanenta pozitia satelitilor.

@@Racov Suna super bine...Ai incercat sa folosesti si un raspberry pi? Eu vreau sa incerc un proiect ca acesta si sa includ mai multi senzori si sa incerc sa controlez totul printr-un server cu raspberry pi. Multumesc mult pentru explicatie!

@@andreiazoitei5387 Nu am folosit niciodata Rapsbery Pi. Pana acum Arduino a fost suficient pentru micile proiecte, si in plus, nu sunt profesionist la programare.

Hello Eric. Please tell me here what is your problem

Ratio

Hi Mauri Yo3rak@gmail.com

Sure

@@Racov ....can i get the proteus connection???

Yes, YO3RAK@gmail.com
