Where's does your loop function end?

Try to find an online tutorial about scope too.

Das glaube ich nicht.

Bei unserem TE herrscht eher eine Art von "Ichbezogenheit" vor, die wie Blei auf der Kommunikation liegt.
Das ist natürlich frustrierend!
Für alle.

Das "Ich" wird nicht bedient und auch nicht hinterfragt.

Z.B. How to use this forum - please read.
Wird nicht gelesen, u.A. weil es nicht das "Ich" befriedigt, und auch nicht unmittelbar zur Lösung beiträgt.
Damit klebt der Frust an den Helfern.
Das akkumuliert sich mit der Zeit.

Denn der TE ist ja nicht das erste "Ich Wesen", welches dieses ignoriert.
Oder besser: Noch nicht einmal ignoriert.
Denn zum ignorieren müsste es ja wenigstens einmal an der Wahrnehmung vorbei gehuscht sein.

You are welcome.

I think your while statement is way too complicated. Basically what you want to do is break out of the while loop if any pair of sensors reads correctly.

Code: [Select]
   while(1) // forever
      if(thisOne && thatOne)
      else if(thisTwo && thatTwo)
      else if(thisThree && thatThree)

      // None of the conditions necessary to exit the loop are true
Project Guidance / APC220 problem
Last post by wenzel3000 - Today at 04:10 pm

Some time ago I bought the APC220 transceiver. To get the thing working, I had to install the PL2303 USB-Driver, but after downloading, I still couldn't select the right Port, because my computer wasn't recognizing the device. I tried several other drivers, but it still didn't work.

Then I thought about using two arduino's for communicating with the APC220. I made a setup according to this Setup ( and it worked! After that succes I tried to send analogue data measurements from a UV-sensor. But instead of receiving the data, the arduino with the receiver just did readings of his own analogue data (measured at his own analogue ports).

After this conclusion I bought the TTL FT232 module, but just couldn't find any information about how to wire and use it with an APC220 transmitter (or any other transmitter).

Could anyone please help me? I am participating with a competition and my work must be done next week.

TTl FT232 module:

It works!
I've been stuck on this problem for days,
thank you!

Do you have details of the actual keyboard, what is connected to each of the wires and the voltage used?

In principle you make a short 'T' cable. The 'T' cable has a female connector, as shown in the photo, which can plug into the vending machine. It also has two male connectors. The cable that presently plugs into the vending machine is attached to one of these and you run a cable from the other to the Arduino. That way you disturb as little as possible.

Whether or not you can use it depends on how many cores are used, the voltages, and what the signals are.

Does the cable in the photo really run to the keyboard? I would have expected the keyboard to be an integral part of the vending machine with no external connection or is that photo from inside the machine?

I am a bit dubious about using vibration to confirm a sale has been made.

Yes they are the same. They are not what.
I suspect you're using int for your experiments. A signed int can only hold up to 32767 and 182 is where you exceed it. Try using long.

GND Pin in PWN Area
GND Pin in POWER Area

I just want to know if they are same or what?

Cuz I want to use GND Pin in PWN Area to do Master/Slave Arduino, because the GND Pin in Digital Area and GND Pin in Power area are already used by CTE TFT/SD Card Shield.
