Good evening to all of you! I'm trying to make an improvised coin acceptor and coin counter. I've found a lot on youtube and on google but i know only basic things on arduino. i made a construction with cartons for the coin acceptor and i've made 4 notches (1 for 10cent, 1 for 20cent , 1 for 50cent and 1 for 1 euro). i've found that i can place a trct5000 sensor inside of every notch , so it can read every coin. Is it right to use that sensor for what i want to do and how i should connect them to arduino? And if it's not, what's the right sensor that i should use? By the way, i forgot to mention that every time i will insert a coin, the value of each one will appear to an lcd 16 x 2.
Thanks for your time!
Is it right to use that sensor for what i want to do
That depends on what you want the sensor to do, which you forgot to state. "read every coin" could mean many things.
You are right about that. As i said i did 4 notches (1 for each coin 10cent/20cent/50cent/1euro). I want to place this sensor i've mentioned before (tcrt5000) on each notch. So when i'll place a 10cent into acceptor, the sensor will "understand" that i placed a 10cent coin. The same thing will happen for the rest of the coins. This will be "translated" propably from the sensor as a boolean value.
What results do you envision when a 10 cent coin falls into the 1 Euro slot?

I've post an attachment below, to see the whole carton "skeleton" i've made. With this way, Paul, i've secured that a 10cent coin will not go to another "way" (each coin which is inserted will follow the specific way i made). So, my questions are: is it right to place a tcrt5000 sensor at the end of each way to read each coin and display it on the lcd?Is there another sensor which is suitable for the case i want?
A tcrt5000 sensor will detect the presence of a reflective object of any sort, within about 3 mm of the sensor.
It can be directly connected to an Arduino, using two resistors. Here is a typical circuit:
I would use a break beam sensor - can be as simple as a light sensor opposite an LED - so when a coin rolls through the sensor is darkened. Then you don't have to rely on a surface being reflective enough or that it's close enough to the sensor.
Guys, thanks so much everybody for ur time u dedicated and for your quick responses!
