Hello Ahmad, thank you again for your EXCELLENT videos! This video is going to help me immensely very soon. I will be having buttons in a steering wheel control several accessories. Since i am limited on how many wire traces can be in the clockspring device in the ateering wheel (sometimes called the airbag spiral cable), this will help to consolidate all my buttons into one wire for each group of 8 buttons (2 wires total for 16 buttons). As well as an illumination wire for the leds in the buttons (from my headlight signal), a 5v wires from my 5v supply, and then a ground wire which might be able to bypass and take a ground from the steering wheel itself as it is grounded. That is amazing because I have 6 wire traces available in my clock spring. Just wanted to again express my appreciation to your excellent , well made videos. Very easy to follow and understand most reasoning behind the project as an inexperienced arduino beginner. Cheers my friend

Hello @hammer7338, I am glad you ound it useful. Actually this was requested by more than 2 persons and then I made the video. I have offered it two versions. you are looking at V2. There is V1 kzbin.info/www/bejne/g5a6mKGqZb5_oJo without the relay and might have some differences. Good luck with your project. Cheers

Can the pushbuttons be replaced with a keypad? I am designing an LED stairwell lighting system with a PIR sensor but would like to implement a keypad that would allow one to activate various different light patterns depending on the button pressed on keypad, ie. 1 = cascading effect, 2 = chasing LED, 3= comet effect etc. I find your videos extremely educational and truly appreciate that you explain the code line by line as it aids me in learning it instead of just assembling things.

[@robojax]

I am not sure how your project works, but I have explained it that the push buttons are connecting the circuit so the voltage is divided, now if you replace it with something else to do the same, I should work.

Additionally no matter you try to trigger in extreme positions the output doesn't change keeping allways on. Something like that sequence (0000/0001/0010/0100/1000). Can you give me a clue how to handling this chalange? tks in advance

sorry I did not understand what you are trying to do .

[@vivekmehta5172]

MIN AND MAX VOLTAGES ON THE VOLTAGE DIVIDER Suppose we need 10 buttons We need 10 resistors in the voltage divider Suppose we use +/- 10% tolerance resistors The voltage on the first tap closest to ground will nominally be 0.1 of the Vcc However the maximum voltage that can be present on the 1st tap is when the first resistor is the biggest ie 1100 ohms and the other 9 resistors are the smallest ie 900 Ohms each The total resistance of above situation will be 9200 ohms and hence the maximum voltage on the first tap will be 1100/9200 of the Vcc ie 0.1196 of the Vcc So we see that 10 resistors of 10% tolerance can lead to almost 20% deviation on the first tap. If we use 10% voltage window in the Arduino code, there is a possibility that there will be troubles in reading the resistors that are closest to ground. I mean, suppose we program that the allowed voltage on first tap is (0.1 of Vcc +/- 10%), but the mathematics say that 10% tolerance resistors can lead to 20% deviation on the first few taps, and we therefore receive a voltage of (0.1 of Vcc + 20%), then the program will not be able to allocate this voltage reading to a button and that key press will therefore be ignored. The way to solve this issue is that for 10 resistors in the voltage divider, the first 4 or 5 resistors of voltage divider closest to ground should be 1% tolerance and the rest can be 10% tolerance. This makes sure that the voltages at each tap are within +/- 10% of the nominal value or better still, all resistors should be +/- 1% tolerance.

Hi I also have another question. I would you add in the code to have a specific button to turn on a specific led or relay to turn on and but then automatically off for a couple of seconds?

[@robojax]

Hi, this could be done in two ways. add delay right after turning the relay on like delay (3000); 3000ms = 3 seconds then turn it OFF and add delay . but this will keep the system waiting until the time is over. the other way would be to use millis() which will not keep waiting . here is the video on millis() kzbin.info/www/bejne/pZOliWyerq1oo68 . all my codes and videos are free. but if you need specific project, you can pay me to wrote code for you. contact me via robojax.com contact page. minimum cost if $100.

Hi there, I was able to get the six relays to turn on but I'm having trouble with the last two on. I first test out with 8 led lights and it works fine then I tired the relays. I was wondering if the adruino board supply limited amount of current depending how many pins is being use or if the adruino board is not receiving enough power or should I consider getting a new 8 channel relay?

[@robojax]

Hi, I am not sure which version of Arduino you have and also how you powered it up. So first measure the current of one relay when it is ON and multiply it by 8 if for example each relay needs 70mAx8=560mA is the total. if you are powering it from USB, then most USBs can supply to max of 2000mA and there should not be any issue. but if you are powering it up via power adapter like 9V or 12V, then the converter on the Arduino board determines how much current is passing at 5V power. Check that 5V converter chip. The best way would be to supply independent 5V directly to the relay module. Search my channel for 8 or 16 channel relay. Good luck

Dear Ahmad, was there any need to debounce the switches ? Were there any glitches due to no debouncing code ?

[@vivekmehta5172]

Thanks Blondie ! Please guide me to time code in video where Ahmad showed noisy switches and where he added debounce code. Ahmad's code is slow since he calculated some values over and over again in his loop instead of once in his setup. Also he added some 100ms delays. Are these delays sufficient to debounce ?

Would it be possible to trigger multiple pins and or send out rs232 commands?

Also need to have it send out rs232 commands on three ports (Arduino Mega). I can only have one button active at a time. Am I going down the right path using this example?

[@robojax]

No sure what you are doing. But you gotta break it down into sending command via RS232, then controlling relay, then timing management. first find a way to send commands and be able to print it on serial monitor. This video is not helping.

[@Seoulhawk01]

@@robojax Thank you for your response. I really like the idea of using analog input and tracking the voltages. I have a code now that I am using, but one of the seven buttons is acting up, and I can't find the reason why. I would be happy to show you the code if you can tell me where to send it.

making 10 push buttons from one input was a revolution that I made. now 45 is extreme but possible with multiple inputs.

[@vivekmehta5172]

@@robojax Following possibilities also exist A) you press 2 buttons, the voltage that is read corresponds to another button that was not pressed, so the action associated with a non pressed button is done. B) it's also possible that the voltage generated by pressing multiple buttons does not get recognised as corresponding to any single button, then the program does nothing.

I wanted ask you, are there lots of code in the loop which actually should have been executed only once in the setup , like the calculations of the expected voltages and tolerances in those voltages ?
