Hi, If i am use 6 interrupt GPIO pins in esp32 and given pulses to all pins on same time then all pins count perfectly or we miss any pulses? For avoid any issues for that any suggestions?
Nayax is a commerce enablement and payment platform. Some of the project use NFC technology. Not sure why you will want to count the pulse from the card reader and to what use? Sorry this is above my knowledge :)
Big thanks for this video. I am looking for a coding that converts the number of LED blinks into a numeric number. Challenge here is that the blink contains two different numeric numbers. Example: for number 24 (to be displayed), the LED will fast blink 2 times and after a short pause long blink 4 times. Any advice will be highly appreciated.
hello brother giving a huge thanks for this video. if i need to display the pulse count in a 16*2 lcd display what should i do. now days i am developing a rain sensor using piezo eletric tranduser i am going to count the pulses using ardunio
You are welcome... you can try the arduino lcd crystal display kit. I don't have a video on using this lcd display. If it's super urgent we can jump into zoom to figure it out after you have all the hardware.
@@codingwithalfred i got the hardware and all other components can you roughly send an email to me to get an an idea about a sample code that i can use to display tyhe count what you are doning in the serial monitor
Using interrupts in such a way does not seem, to me, to be an efficient method of programming. Couldn't you just use a binary ripple counter (such as a 74hc4020) and save on the interrupts?
Depending on what type of rotary encoder you have. Fundamentally as long as your encoder is producing a pulse wave good enough for the digital pin of the Arduino to count (if the encoder is a high dc voltage device, you can reduce the voltage via a divider schematics). If you have a specific situation that you are dealing with. Please, let me know the details, let’s work through it.
@@codingwithalfred I am a final year student and my project involves in detection on a pulse from the encoder and displaying a output. Basically we are using this as a selection bar pretty much like the lcd screen. The encoder that I am using is 16ppr encoder, naming RHSS - 40 Could you help me with the programing part majorly
@@mahimakulkarni4107 16ppr encoder have a few variation. Do you have the model number/name? Looking at PEC11H Series - 11 mm Encoder w/High Detent Force. The code on the video will work for it (ie it will detect the pulse) the contact rating is 10 mA @ 5 VDC. I am not sure what you mean by "Basically we are using this as a selection bar pretty much like the lcd screen"? If you need to detect the pulse and display the count on an LCD display, then all you need is to write the total pulsed counted to the LCD display module.
@@codingwithalfred the model number is RHSS -40 and right now I am wanting to detect a single pulse to begin with then will be using the switch case to display the output but the difficulty I am facing is that the pulse detection isn't happening the way it needs to for me to further move forward. Can you share your email address so that I can send the pic of encoder and my code for you to have a look?
@@mahimakulkarni4107 I looked for RHSS-40 and could not find it. Do you have the datasheet for it? Perhaps you can send me a copy or point me to a link to download it? Absolutely, i will be happy to take a look. Here is my email: hiiasolution@gmail.com . I think i understand what you need, it should be straight forward detecting the pulse. My guess is that maybe the setup is not configured correctly. As soon as you get that part right, then based on the pulse count, you can now use a switch case to display the messages you want to show on the LCD. All this will be done by code and its very straight forward to do.

Lots of good content
Good job mate

Wonder if this could work with a Nayax card reader pulse output
Never heard of that. I will look into it.
Nayax is a commerce enablement and payment platform. Some of the project use NFC technology. Not sure why you will want to count the pulse from the card reader and to what use? Sorry this is above my knowledge :)
i was here researching how to take a Nayax pulse and convert it to opening and closing a relay - I know its possible to use ardunio to count it.

Indeed... might be a good idea on a future project.
You have online class
No, What type of Arduino lesson will you be interested in ?
