Control lcd with two tact switch and ir remote

cakemecakeme · May 6, 2022, 4:16am

Hi everyone, I am having a trouble making code for my project. My project is a "TV like controlled". I should control LCD with two tact switches (push buttons) and also with IR remote (both have the same function) please help me

Hello cakemecakeme
Welcome to the forum.
Post your current sketch, well formated, with comments and in so called code tags "</>" and a schematic, not a Fritzy diagram, to see how we can help.
Have a nice day and enjoy coding in C++.

here is my schematic and code, thank you so much

Hi, @cakemecakeme
Welcome to the forum.

I'm sorry but this does not make sense.
switch
What are the R1 and R2, 330R resistors for and why have you got them shorted together?
S2 and S1 are connected to what?
What do all the

Can I suggest you forget about the CAD and draw it by hand showing ALL connections and ALL components, don't use all net names for such a small project, connect ALL wires.
Gnd, 5V and 3V3 can be netnames as we all know they are common connections.
Where is your power supply?

Sorry mate, but for a first try is a good attempt, but try to stop wires circling around components like R4.

I hope you have not had a PCB made.
A picture of your project would be good.

Thanks.. Tom...

Hi,
I think this will make things clearer:

R3 and R4 the pulldown resistors are best as 10K resistors, rather than 330R.

hello i tried but its not working

groundFungus · May 12, 2022, 3:01am

You tried what? "not working" conveys no useful information. What does "not working" mean? The code does something, tell us what.

Does the LCD work?

The resistor on the LCD pin 3 (Vo) should go to ground, not 5V.

The IR receiver should be powered by 5V. What is the part number of the IR receiver?

You read the IR signal but do nothing with it. Do you know if the remote works?

What version of the IRremote library are you using. The code is written for an older version of the IRremote library and may not work right with the newer version.
