Can someone help with this code i'm new to arduino and i don't know what i'm suppose to do, there's always an error while uploading the code

#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();

void setup() 
{
  Serial.begin(9600);
  mySwitch.enableTransmit(10);
}

void loop() 
{
  int value = analogRead(A1);
  value = map(value, 0, 1024, 0, 180);
  mySwitch.send(value, 30);
}

avrdude done. Thank you.

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

you code seems to compile OK but the upload does not work.
Have you selected the right board, the right boot loader if it is really a Nano, the right port? does the cable work? etc...

thank you for the quick response. J-M-L
the cable is working just fine, as for the other's i'm not too sure as i just copied the code and just followed the step by step process that he posted.
just to take note, i just started using arduino for my school project so i'm not well verse to any of this.

Is the board really a Nano ?

are you able to open the blink example and upload it to the board?

if you look in the menu Tools / processor you get to select the target board:
image

you selected Old Bootloader. May be your board has the new boot loader and so you should pick the first entry

i tried using that one a while ago but the result was still the same.
the difference was the this time the code was uploading for almost take 1-2 minutes but the result was there's still an error.

An error occurred while uploading the sketch

i got the codes from this website: 433mhz RF Transmitter and Receiver module with Arduino - SriTu Hobby

the problem is not the code; it compiles. the problem is your PC/Mac does not manage to upload to the Arduino

  • Is the board really a Nano ?
  • is it a clone? what serial chip is used? do you have the right driver if it's CH340?
  • Do you see it on the USB bus when you plug it in?
  • how do you know your USB cable is good?
    ....

  • yes, at least that's what i think.
    -it should not a clone as the store that i brought it from is a reliable store.
    and what does the driver means?
    if it might a clone what will happen to it?
    -as for your third question, does it have a indication when it is plug in because i didn't see any.
    -and lastly i assume that the cable was working because there's light on POW and L is blinking from time to time.

OK from your questions I can conclude what your knowledge level is.

The communication between your computer and the arduino-nano runs over a chip that does a protocol-translation from USB-protocol to serial-protocol.

This chip has the name "CH340" You need to install the suiting USB-driver for this chip on your computer.

If this driver is installed successfully can be checked in the device-manager of your computer.
the device-manager is a software that you can start on your computer

if you have started the device-manager there is shown a big list of all the devices inside your computer. It i smuch more than you will have estimated before you saw the device-manager the first time

You need to open the section with the name connections (COM & LPT)
and to look there if there is an entry CH340 UART bridge (COMx) where x is the number of the COM-port.

If there is no entry "CH340" you have to install the suiting USB-driver first
if the USB-driver is installed you have to adjust the comport in the arduino-IDE

here is a step-by-step-tutorial

thank you. StefanL38

thank you for your help guys.
J-M-L Jackson and StefanL38
i was now able to upload the code. :smiley:

So it was the ch340 driver?

have fun

yeah it is, i was not aware that i needed earlier when i started coding.
anyway thanks for your time.

btw J-M-L can i ask a question if i can integrate the timer relay to arduino, because i need to have an off delay to the servo motor.

not sure what "the timer relay" is, but your Arduino can definitely process time and issue orders to a servo. requires just some programming

oh is that so, hmm will i have to add it to my existing code or something? and how?
and do you know any code that i can use?

I don't know what you mean. delay() will create a delay for example

You should probably open a new question , describe what you have, what you tried, and what you are trying to achieve

read How to get the best out of this forum to understand what's expected to get meaningful answers

you seem to be right at the beginning of learning to program. A microcontroller can do almost anything except mining bitcoins and painting elephants pink. (no this is an exaggeration)

But for real microcontrollers can do a lot of things and timing switch on/ off something once every 0,01 seconds or just once per hour, once per day, or once per week is a piece of cake.

So yes please make write a description of the functionality that you want to have.
Write the functionality-description with common words. Avoid programming terms because you know the meaning of the common words.
You may have some misconceptions about programming the common words assure that your wanted functionality will be well understood.

best regards Stefan

I suggest you first run an Arduino example program. The best for a "is all working" test is the"Blink without delay". It if found under Files/examples/Digital
