We can store the position of the servo and the direction of travel every time we move it. This can then be recalled when we power up. However since the Arduino does not know how long it is powered down for it has to assume that the next event will take place 5 minutes after power up and that this event is the next in the sequence of 0, 10,20,30,45,30,20,10,0 depending on what the last sequence position was stored in the EEPROM.

Cheers Pete.

Hello ,

This is not difficult but one question on something that is not clear. Since you are intending to turn this on and off with a power switch and it is not staying on all the time real-time events will not be possible. The Arduino does not have a battery backed RTC and so its timers would start at zero every time it was turned on and it would have no idea about the passages of time whilst it was turned off. If the loss of real-time is not important then you can store the last known position and direction into the EEPROM and then when the next  5 minute event takes place after power up advance it from there.

I can write it for you very quickly. Do you have a budget in mind for this.

Cheers Pete.

This is an interesting project.

I am interested in working on this with you and  I have sent you a PM.

I would pick up on one thing however .. The Emergency stop button needs to be instantaneous and NOT subject to a 2 second delay. It also needs to be on a closed loop circuit and independent of anything else. Closed loop so that it is active if the cable breaks. I would suggest that it forms part of the relay control to the motor and not be part of the MCU. You would not want a program failure to prevent the stop from working.

Cheers Pete.

I am able to help you and have the skills you are looking for. Expand a a little on your requirments and I'll see if I am potentialy in or not.

BTW it is not good etiquette to cross/multi post, you will anoy a lot of folks here doing that.

Cheers Pete.

I might be, if you need my profile go look at my website

I am assuming RC has its usual meaning and that money really does mean money.

Firstly this needs to be in English language as you have written to the English speaking section of the forum.

Now I am not sure i understand what you mean by interfacing a 900Khz antenna to the Arduino.

Long distance RFID reading can be done but with large antennas and they are normally arranged in a loop.

RFID tags are parasitic devices and get their power from the reading coil of the reader.

Well folks I feel I have to post a cautionary note here on this project and person.

Mario and I had a long a protracted conversation about how he might get this to work on Skype (he has provided his Skype address int he original post). I pointed him at several options and spent about 2 hours chatting and explaining how things might work. The result of all this was that he then commissioned me to write the firmware. I did this and sent him via email as requested a video of the finished product.

Since then I have heard nothing from him I sent a few more emails and left several messages on Skype. I even tried reaching out on his websites. He has shut down his Facebook account (address also posted in the original post) and not responded to a single attempt to contact him.

Now fortunately I have only wasted my time here and nothing else. However it serves to qualify the reason why  I ask for a 50% deposit on my development fees when taking on work.

So if this person should crop again asking for help you have been forewarned.

Cheers Pete.

The Original poster also cross posted this to Gigs and collaborations offering to pay for help. I helped and wrote some software as he asked me to do then he shut down his Facebook account and refused to answer any further emails.

Hi Mario,

Code complete and a video of it working sent to your email address as agreed.

Unfortunately you don't seem to have a Facebook page anymore and you are not responding to my Skype messages.

Cheers Pete

Hello Mario,

I have sent you a PM on FB and a contact request on Skype.

Cheers Pete.

or even piezo strips, you will need to condition the output as it can get quite high but a simple resister and zener diode clamp to keep it below 5v will do you. the pulse will be quite quick but not too quick to be caught by an interrupt set up for edge detection

Luckily I'm a semi-fast learner

Then carry on learning until you get it sorted.
SHOUTING at people you are trying to elicit the help of will get you zero results.

HI Jeff,

Why not post your code here and get some help for it. If you are reticent to do that post it to me in a PM and I can take a look at it for you .

Cheers Pete.
