Slot sensor arduino

Slot sensors, sometimes called optical fork sensors because of their "forked" shape, detect objects that pass between the two arms—one with the emitter, the other with the receiver. The fixed slot width provides reliable opposed-mode sensing of objects as small as mm. If you do not see what you are looking for, Ask an Expert.

Once the program is uploaded, click the Serial Monitor button to see the values changing as you cover and uncover the photoresistor. If you do an interesting project about encoders or robots. But encoder not give proper constant value,its values change very fastly at every instant. Customers recommend. I found it hard this time to find the info I was looking for its connection so here is the link for the pinout. Send Cancel. PVA provides most reliable solution for error proofing.

Once the program is uploaded, click the Serial Monitor button to see the values changing as you cover and uncover the photoresistor. When the values go above , the vibrating motor will vibrate!

To program this microcontroller, you need to use an USB to Serial converter. Since the Lilypad doesn't have headers soldered to them for easy prototyping or programming, I recommend using alligator clips. First get female headers , then cut 4 off of the strip, and solders wires to each lead. Then press the Upload to Board button in the Arduino programming environment, then press the Reset button on the Lilypad Arduino, and watch the program upload.

Once uploaded, we can start making the Coin Slot Detector! First: Thumbs up, cool project. Reply 11 years ago on Introduction. Not sure what part of England you come from, but in my part we call it builders bum, so much more polite Reply 8 years ago on Introduction.

Pages: [1]. LavenderSmile Guest. Slot Sensor with Arduino. Hi I am trying to use an optical slot sensor with the Arduino to sense a coin drop and I can't find any schematics for the part.

KeywordSearch, from the opbseries. Has anyone used this part before? Does anyone have any idea how to set it up. Re: Slot Sensor with Arduino. You have an LED and a phototransistor. When the LED is powered and nothing is blocking the light the phototransistor will conduct in one direction. If the LED is not powered or something is blocking the light then it will not conduct. Take a look at the wikipedia article on Opto-isolators, that is basically what you have except something can block it.

R2 is a little trickier. I think I'd size that for a 1mA current flow, no need to get crazy with the power use, maybe a 4. You might need to play with that a bit to balance out the sensitivity with varying ambient light levels.

So to continue, if you connect an input pin between R2 and the phototransistor then it will be low until a coin slides by when it will blip high. You must poll very fast to catch it or use an interrupt pin. Another possibility instead of an interrupt or fast polling is to use something like a in one shot mode to trigger a fixed duration pulse.

This pulse could be milliseconds long. Depending on your preference you could trade software complexity for hardware complexity. Magneon Guest. I would suggest a simple mechanical device such as a really weak leaver that would just break connection while the coin goes through. I hada couple of mice old ball mice, not new optical style apart yesterday, and they both use slotted a encoder wheel, LED, and phototransistor for each axis.

Games involving matching up lines of gems are huge these days, especially as smartphone apps. Cool Jewels from WMS and is a slot game which combines gems type play with the chance to win real money. You can find this game in live casinos as well as online.

Instead of a normal set of slot reels, this game is played on a 6 by 6 grid. Groups of adjacent gems trigger wins, and also disappear — allowing more gems to fall into their places and potentially making more winning combinations.

To add to the interest, wins get bigger the more combinations you hit in a row. There are also special symbols which have different behaviours — these can explode and so on.

To add another level of interest, when these special symbols combine, things get even more interesting! Each time you spin the jewels will be replaced completely and winning combinations assessed. These need to be side-by-side and not corner to corner. These symbols will flash and then explode, allowing the others to drop into the holes and new ones to appear at the top of the grid.

The first win gets you 1 coin per symbol, and each time you get a winning combination on the same spin after that, the win amount increases.
