12/31/2023 0 Comments Cycle through a switch case arduinoPhase 1 &2 works perfectly fine, no glitch whatsoever. From there I want to animate another time with the sine waveform fade in/out again except this time it wont go down to 0% but instead a 'brightness' value.Ĥth phase: Here I used a fade in/out without the loop to keep the same brightness all the time.Īll seemed goos to me but I have a weird behaviour if I run the program. For those who wonders how, here is my source and the reason why I used radians.Ģnd phase: I used twinkle effect to indicate that the RaspberryPi is starting and then connects to my NAS serverģrd phase: Once connection is established, the RaspberryPi update an output to inform the Arduino that the connection is OK. I replaced the ramp with a sine waveform. I want to cycle through phases:ġst phase: I used fade in/out effect to light up from 0% to 100% (I actually don't use 100% because it's making too much light) and then back to 0%. Bookmarked! I believe this helps a lot of people getting started with these and the time and patience you took to right it makes it all very educational! Unfortunately for me I suck a lot at VHDL and during my struggle with it I came across your website and more precisely FastLEDs effects article. In the first place I wanted to use basic LEDs with PWM to modify their brightness in VHDL. I am currently working on DAC design since last year. So I answered my post and probably trigger an anti-bot detection which got rid of all the explanations I had written. But, I don't think I'd use switch/case statements.I posted on the effects article saying I would create a topic but there was something wrong, I couldn't. ![]() I don't want to tell you how to write your program, especially if it's working so-far. I'd start with the timing "delays" and then add the other features one at a time (in whatever order makes sense to you). I'd recommed simply attacking these one at at time. You only need to turn-on one LED, and/or turn-off one LED each time, and you only need to "write" when something changes, such as a time-up state, or when a button is pushed. I haven't completely studied & analyzed your code, and I'm not going to try and write your code for you.Īfter setting-up the initial condition (all LEDs off?), there is no need to write to all of the LEDs in each "case". You might want to choose 3, 5, 6, 9, 10, 11.Ĭurrently i am using an inventors kit to prototype my code before i start buying parts or anything like that. I should point out that on the Uno not all the pins you mention can do PWM. ![]() Now that turning on the right LED, to the right brightness, is a single line, I'll let you play with automating it. Void turnOnLED (const byte which, const byte brightness)ĪnalogWrite (ledPins, brightness) // make "which" zero-relative Let's get rid of those dozens of analogWrites: const byte pinCount = 6 Ĭonst byte ledPins = Here is my current code: const int ledPin1 = 5 I was hoping someone could give me some guidance and help me solve my problem. However, i have run into some issues with an automatic cycling feature. Currently i am using an inventors kit to prototype my code before i start buying parts or anything like that. I am working on a project that is supposed to light up 6 different panels on a wall mounted board individually. Pushing the button again while an LED is frozen should reset to case 1 and wait for a button push.If the button is pushed while an LED is lit, that LED should freeze and stay lit.It should then reset to case 1 (no lights) and wait for a button push.Pushing the button once should cycle through all the cases from 1-7 with a 3 second delay on each case.The missing code needs to do the following: I've put a comment in the code where the function that will cycle the cases should go. If the button is pushed during this cycle, the LED should remain lit until the next button push. ![]() ![]() Mode 2 (automatic) should cycle through all the cases, then reset to a neutral state. The case switch statement is used because i want to be able to modify the brightness of all the "off" LED's. Every time i push the button, the case increases by one, as it should. Statement that will cycle through all cases with a 3 second delayĪs you can see, I have a master toggle switch that determines which mode the LED's will cycle in (single or automatic). Hopefully this post will clear up any confusion and provide an idea of what this project is supposed to do. I apologize for my lack of clarity and forethought in my initial post.
