Customer:
I have a Croduino Basic from 2013 that hasn’t been used for a long time. When I connected it to a PC with a suitable USB cable, no lights turned on as if it were connected. Could it have stopped working from being stored?
I also have a few questions:
- Do you have inductive sensors in your product range?
- Can they be connected to a Croduino and provide a signal indicating whether detection occurs or not?
I’m working on a project involving a pneumatic planter. I’m interested in whether there’s a sensor that could detect corn kernel drop-off, and after some time without kernels being dispensed, it could trigger a warning light signal?

Poštovanje, imam vaš Croduino Basic iz 2013 godine, koji nije korišten duže vrijeme. Kada sam ga povezao preko odgovarajućeg usb kabela na PC, nisu se upalile na njemu nikakve lampice kao da je povezan. Jel je možda od stajanja otišao? Još par pitanja.. I jel se oni mogu povezati sa croduinom i tako davati signal ima li potvrde ili je nema? Radim nekakav projekt na pneumatskoj sadilici.. Pa me zanima postoji li kakav senzor koji bi detektirao ispadanje kukuruza i tako bi nakon nekog vremena ne sipanja kukuruza bacio na žarulju signalizaciju?

That’s an early Croduino unit. If it sat in a relatively damp location, it may no longer work. Otherwise, it shouldn’t simply stop working, but if it has, the problem is very likely in the USB connector. Without seeing the board in person, I can’t say more.
We do stock some inductive sensors (check the FOTEK sensors in the position sensors category): Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
For detecting corn kernel drop-off—detecting kernel presence—optical detection is the simplest solution, using either a photointerrupter or a laser plus light sensor: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics

hvala na javljanju!
Hmm 2013.g. - prije 5 godina 
Mora biti da je to jedan od prvih Croduina. Ako je stajao na relativno vlažnom mjestu, moguće je da više ne radi. Ovako inače mislim da se ne bi trebalo dogoditi da prestane raditi te ako je prestalo mislim da bi vrlo vjerojatno mogao biti problem u USB konektoru. Nažalost ako nemam pločicu ispred sebe, više od ovoga ne mogu reći..
Imamo neke induktivne senzore(pogledajte Fotekove senzore u ovoj kategoriji): Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
Ispadanje zrna kukuruza, tj dakle prisutnost zrna je najlakše riješiti optičkom detekcijom, možda između fotointerruptera ili putem lasera + senzor svjetlosti

Customer:
What are the differences between FOTEK PL-05P, PL-05N, and PS-05N? Could I use an inductive sensor to measure the rotational speed of a shaft?

Koja je razlika između foteka PL-05P, PL-05N, PS-05N? Bi li mogao putem tog induktivnog senzora mjeriti brzinu vrtnje neke osovine?
Soldered Support:
All the solutions I’d suggest are probably easiest to implement with a Croduino.
You need to put a bootloader on a blank ATmega328 chip and then program it via serial communication.
For the differences between FOTEK sensors, see the datasheet: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
The difference is in the type of output they provide and the distance at which they detect an object.
You can measure shaft rotation speed with an inductive sensor if you mechanically arrange something that will change the sensor state with each rotation.

sve solucije koje predložim vjerojatno će biti najjednostavnije realizirati s Croduinom.
Trebate staviti bootloader na prazni atmega328 chip te ga onda programirati putem serijske komunikacije.
Za pitanje “Zasto mi ne nudi promjenu portova?” niste dali dovoljno detalja kako bismo mogli odgovoriti. Gdje? Kada?
Razlike između FOTEK senzora potražite u datasheetu: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
Radi se o razlici na kojoj daju izlaz, udaljenosti na kojoj detektiraju objekt..
Možete ako mehanički napravite nešto što će mijenjati stanje senzora svaki okret.
Customer:
Can I power a FOTEK sensor from the Croduino? I see the FOTEK has a minimum voltage of 10V while the Croduino outputs 5V. Do you have any example code using a Croduino and FOTEK sensor? I see from the datasheet you only have a FOTEK that detects at 5mm—do you have any with 8mm or greater range?
Original message (Croatian)
Mogu li napajati Fotek preko croduina? Vidim fotek ima min napon 10V dok nam croduino daje na izlazu 5V? Imate li kakav program s croduinom i fotek senzorom? Vidim prema datasheetu imate samo fotek koji detektira na 5mm imate li od 8 ili vise mm?
Soldered Support:
We only stock the sensors you see on the website.
You can power them from a separate 10V or higher power source, or you can step up the Croduino’s 5V using: Regulatori napona | Moduli za konverziju snage – Soldered Electronics
Original message (Croatian)
imamo senzore jedino koje vidite na webu.
Možete ih napajati iz nekog trećeg izvora koji je 10V ili više, ili dići 5V napon s Croduina koristeći: Regulatori napona | Moduli za konverziju snage – Soldered Electronics
