Hi! thanks in advance.
I am a novice!
I have inexpensive IR LED transmitters and receivers.
The receiver (the clear one I believe) returns 1.1 v and OL for resistance which seems fine.
the transmitter returns OL for V and some 40kohms for resistance + to+ ; and 1kohm + to -
what v should I apply to each, can you point me please to a breadboard visual and a circuit diagram?
thanks!
IR recievers do not work on simple levels of IR light. Signals are pulsed on top of a 32 to 42KHz pulsed modulated signal. You have to know what parts you have in order to stand a chance of working things out.
Look at this :- Receiving and Decoding IR | Using an Infrared Library on Arduino | Adafruit Learning System
What do you actually want to do?
Thank you for your direct response!
Apologies for "opening my soul"!
Electronics is deeply and intimately complex!
My name is Martyn, I am retired, would like to develop the ability to learn about Arduino and how it can be used in association with electronics projects.
I have worked in depth through various books, understand in principle many of basic electronic and programming principles.
the books are so very informative in terms of projects to follow but when I get to try this one for example I am completely stumped!
On line courses just seem random and unfocused.
What I basically need is a HND course in electronics but that isn't feasible.
If you can point me where to go to get basic training that will be amazing. I do not seek a free lunch ticket and am very willing to pay for something if it can achieve the result.
Thanks for listening and apologies [again] for the prolonged rhetoric on my part!
Sorry; my previous posting was not properly defined!

If you want some basic electronics knowledge... take a class or grab a book.
(there are also tons of on-line assets available)
For Arduino specific stuff... maybe start with the basic Arduino tutorials here or on the Adafruit site.
Tronixstuff and Jeremy Blum sites also have some great tutorials..
EdX courses and similar are widely available these days and you might find the right level of course
there. The discipline of a timed online course with homework is really effective I find.

The first thing to determine ---- as usual ---- is what level you are at in terms of your experience..... eg. electronics fundamentals level, maths level, programming experience level. You mentioned you went through various books. However, at the moment, nobody here knows what you learned from those books. It's necessary for you to first convey a little bit about what you currently understand..... or what you can handle so far. Eg........ can design and build a circuit that lights up an light emitting diode (LED), or design and build a circuit using that makes a DC motor's shaft spin around when you depress a button of a switch, and stops the motor when you let go of the button etc.
And, indicate whether or not you've programmed any kind of microprocessor module before. Like.... have you done something like make an arduino light up an LED, and make that LED blink repeatedly?
Electronics is a big subject, you never stop learning and something new is constantly being invented.
If you want to get to grips with the Arduino then the best bet is to get a starter kit. These come with the hardware you need for several projects. These kits are not always the best at explaining why you do, but are good at the what you do. However we are always on hand to explain things that puzzle you.
