Hello, I have a project that requires some C++ code for my Trinket. Would appreciate some feedback from knowledgeable Arduino programmers to answer a few questions. Can the Trinket process a Sketch that has several operations running in loops? Examples of what I want a: Monitor 3 momentary pus…

Hi @vcholman Yes, all this is possible on a Trinket Pro 5V. [image] Introducing Pro Trinket Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in, so deli…

Hi, All good information. Some of your concerns should not be a problem in my case. I am using the Trinket Pro 5 volt Output current limitation is not a show stopper. Outputs will be triggering transistors, which will provide the current for driving output devices. Serial interface is not neces…

[image] vcholman: My loops have delays, which I have learned no one likes. The reason why 'no one likes' is that delays make it close to impossible to achieve what you want to achieve.

As you haven't shared your code, below will probably be more or less what your fade code looks like. int fadeValue; const int ledPin = 6; void setup() { pinMode(ledPin, OUTPUT); } void loop() { for (int cnt = 0; cnt <= 255; cnt++) { analogWrite(ledPin, fadeValue); fadeValue += 5; …

Sterretje, Your fade up/dn sketch is very close to what I want. I don't want the led turning off. It goes to full brightness, steps down by 5 to zero. Then backup. fadeStep if I'm correct changes how many step at a time the loop ramps from 0 to 255. And the fadeInterval is the step rate. When I c…

Sterretje, Here is my not so efficient fade sketch, it has delays. But the fade up/dn brightness levels and rate are what I need. int ledPin = 9; //LED connected to output digital pin 9 void setup() { // Nothing happens in setup } void loop() { // fade in from min to max in increments of 1 …

Sterretje, Once I understand how to modify your fade up/dn code as listed under the "the complete code" so my led doesn't turn off. Remember I would like the fade to start at 10 percent and top at 100 percent. Then fade down from 100 percent to 10 percent, then repeat. Once I have the fade up/dn c…

[image] vcholman: fadeStep if I'm correct changes how many step at a time the loop ramps from 0 to 255. And the fadeInterval is the step rate. fadeStep are the increments; in the original code wit goes 0, 5, 10, 15, ..., 250, 255, 250, 245, ..., 5, 0, 5, 10 etc. You can observe the values in …

[image] vcholman: Once I have the fade up/dn code working, would you please provide the code to randomly blink 3 LED's so I can see how the two separate codes work together in a single sketch. /* randomly blink three leds */ void random3() { // time when an update of the random leds is re…
