Some 35+ years ago I had taken a class in Electronics, so I know some basics, but alas I've probably forgotten most of it. Please excuse the novice level of the questions.
I'd like to try my hand at a small project building a set of flashing LEDs. The general specifications are:
- On-off should be about the same duration
- Frequency will be 10hz to 40hz (not khz!)
- I'm considering using something like
https://www.amazon.com/Chanzon-100pcs-Infrared-Emitter-Emitting/dp/B01BVGIZIU
I want to use a couple of different LEDs ( 1 part red (660nm) to 2 parts (850nm) )
I've looked at
https://forum.allaboutcircuits.com/threads/project-flasher-circuit.7779/ and
https://forum.allaboutcircuits.com/threads/project-high-power-led-flasher.32364/
I'm not sure whether I would need a high power project or not or how to identify when it becomes high power.
Also I'm trying to find a quick "kit" on Amazon to get me going. What would be the minimum I would need to get to start out in the way of a kit?
If I don't have an oscilloscope or something like that, any idea how to identify the frequency that is actually being put out?
And if I want to make multiple LEDs flash together, would it be better to put them in parallel or serial?
