@Paolo-Moro 0n Arduino Dock 2 the 5V of the Expansion Header is same as the Input 5V (provided by the micro USB or the Barrel Jack) - ie. each 5V on the Dock is common.

Hey György, oh man... that wasn´t worth to open a topic... I just grab a NPN and it works. Thank you very much.

The Omeage2 has no analog, limited PWM, non-deterministic timing. Arduinos have a varied number of analog, digital and PWM pins, are deterministic as to how long things take to run, have 'bank' i/o support (which I've not seen implemented on any copy device), software serial, sleep mode, ... So, no.

The Omega2's do not have a real time clock (RTC). So at start up, they have a default time which increments until such time as a network connection has been established to the Internet. Once the Omega2 has sync'd to an NTP server, the time should be accurate per your Omega's timezone setting.

@Uzair-Shafiq You should install screen opkg update opkg install screen Connect to Omega with ssh and run screen: screen /dev/ttyS1 9600 Now you should see the output of those Serial.print on this Arduino IDE Serial Monitor like "screen". To kill this screen session, type Ctrl-a then k. See also: Onion Omega2 Documentation Communicating with Serial Devices Using the screen Command Good luck!

@Victor-Iriciuc Victor, glad you found the ticket system. and you are correct to post here in the forum to discuss the current status of your issue. i was just saying that to get official help you need to enter your device in the system. be sure to list url's of any threads you tried to get help in. the onion admins can then read up on the status of any help that was discussed and hopefully make additional comments and/or suggestions.

You have right. The sensor is dead, i replace it and it works fine.

@Douglas-Kryder Thanks for the answer. I just wanted to be sure they worked before I paid for them. I'll get them on payday and start messing around with them.

I am still having a very similar problem with my arduino dock and have not resolved it as yet: https://community.onion.io/topic/2177/arduino-dock-error/ Maybe one of the comments given will help you figure it out. If you do please let me know how!

@Lars-Flikkeid said in Arduino Dock fried. Is it possible to repair?: @György-Farkas Also it seems that the atmega is just connected to the 3,3V and not the 5V, and maybe it therefore was protected since it never was in direct contact with 12V. All power pins of the ATmege328P-AU (VCC pin 4, pin 6 and AVCC pin18 of the 32-pin TQFP package) are connected to +5V (ie VIN, USB VBUS) on Arduino Dock 2.

Hi @Wayne-Holloway ! Can you read the water flow directly in omega GPIO or you need to connect them to the arduino dock ? I can't correctly read my sensor because I don't know how to do this by omega GPIO interrupts. Best regards!

No and you can use them without. Kickstarter was quite clear what you pledged for.

@Douglas-Kryder said in Omega 2 and Arduino dock.: @Gamaliel-Valencia well, if the thing is still within any type of warranty framework then i would put in a ticket for return, mention the thread so if they have any ideas over what has already been discussed they can join in. but it seems to me you have tried all that you could. other boards have just not responded as well so some of them just may be broken. wish i could offer something else but out of ideas. @Douglas-Kryder I really appreciate your support and I think you are right, I will send my ticket and wait.

@Visti-Stenmo if it helps, here's a tutorial https://ubidots.com/docs/devices/omega.html#onion-omega-and-ubidots

@Matthias-Nowak thanks i want to connect 2-3 motors (with driver module i guess) and few sensors, omega2 + expansion dock can handle this?
