Hi I am pretty new to XOD but I love it more or less already - I am not the big “coder” - therefore very good for me 😉 Working on a project and needed a blinking sequence of a single LED. Found on Youtube a video where someone was creating a morse code signal - voila - exactly what I need ! Rebuild it and not working: My problem is that some sequenced flashes of the LED are bright (OK) - some are dimmed (not OK) tried everything - shortened, longed the flashes - swaped the long and short ones in order - no success. Am I doinng something wrong or is it a bug ??? In the Video it works great. Made it with “Flip-N-Times” nodes (being on Active False), fed this ACT via “pulse-on-false” and a delay to the next stage, sequnce of “Flip-N-Times” Routed the end DONE via a “defer” and an “ANY” to the first stage to create a loop. Mainly the sequence works ok - but like described - some flashes are dimmer, sometimes it looks the LED stays on and dimms down for certain flashes - I give up 😉 Anyone some help ? Cheers Marty ---

Hi, can you upload the xodball and the video address you refer to? ---

Xodball ??? you mean the file ? sorry dont have it anymore - started building it exactly like in the vid. and then thousand changes - no luck 😉 the video on youtube is called: XOD Tutorial 1\_ Getting Started ---

XOD has changed a lot since the publication of that video, what would you like to do? I see how I can help you 🙂 [blink-multi.xodball](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/f0b216be8833fb0376c2dbb3045aa73acb69e8b3.xodball) (7.6 KB) ---

thanks a lot - Oh I see therefore the “old” tutorial is noch working 😉 your file workes good - thanks a lot - I changed a few values and made it to my need - although its tricky with the delays One big question: I made a longer loop out of more sequences of yours with two different LEDs. There is still, that a few of these “branches” of the loop is dimmer, other ones are full brightness - does this has to do with non exact delay values that there is a bit of overlap etc ? Its not important - I am happy as it is right now - would be just curios to know. For me as a “non coder” - XOD is the perfect thing - never got so much into arduino ever - like it. Next project is connecting the whole thing to bluetooth - are you experienced in that topic too ? Thanks a lot cheers Marty ---

My 1st guess would be that you have multiple LED nodes with the same port and somehow your code is trying to activate more than one of these at a time, so the LUM value for the port is bouncing between on & off, causing LED to not be full bright. ---

I upload a new more configurable example [blink-multi-3.xodball](https://forum.xod.io/uploads/xod/original/1X/7b60cf58bdae7c2b8213aa51509f06c389eb4b6c.xodball) (28.3 KB) **update** , comments and an identical patch without buses were added thanks you @gweimer ---

@ gweimer: yes I guess so too - too many delays steppen on echt other toes 😉 @ cesars: wow the new Blink looks complicated - Ill give it a try tried to attache my novice version for the multiblink with 2 LEDs - but it says as a new user I cant upload anything but nevertheless, thanks for your help ---

> [@cesars](#): > > I upload a new more configurable example Cool code, but you might want to add come comments for beginners. Is there a reason you used bus to feed if-else-v instead of moving it below the defer nodes? As a quick overview: - the “clock” node at the top allows you to set how long between blinks (each “tick” starts a new blink). The “delay” node feeding into it specifies how long after boot before blinking starts (5 seconds) - the nodes feeding “led” node cause LED to be on for 1st half of each “tick”. You could change the divide value so on-time is more or less than 1/2 of each tick. You could even add another “if-else-v” to change the on-time during the pattern. - the “between” and “greater” nodes feed “if-else-v” to determine how long each “tick” is. (The 1st 5 “ticks” are 0.5 seconds; next 5 are 1s; last 5 are 2s). You can expand if-else-v and add more conditionals to make more complex patterns. - the “count” node counts how many blinks we have done. The “equal” node feeding into it resets count after 15. (Since count is a number, which could be fractional, it would be safer to use greater 15 instead of equal 16; this is not as critical since we are just adding 1 and not doing multiply or divide) ---

The “delay” node feeding into it specifies how long after boot before blinking starts (5 seconds) As it is an example I thought it was good to add more nodes, it could be 1 second or descactivate it Without the delay, the first ones are almost not seen if the console is used > [@gweimer](#): > > - the nodes feeding “led” node cause LED to be on for 1st half of each “tick”.

Update with comments and add a patch without buses. When doing the buses using counter output, there are no names, if there are several meters, the `number` buses are mixed and you have to put them manually.
