How Long Does It Take to Upload Code in Arduino
Every bit an electronics engineer getting dorsum to my roots with Arduino, I found it could be a little confusing getting started uploading lawmaking (or sketches) to an Arduino. Installing drivers, IDEs, and everything else involved wasn't a straightforward task. And so I put this guide together based on my experience uploading lawmaking to a new Arduino on a new computer.
This guide is a pace-by-step (with pictures) on how to upload and run code on an Arduino using a Windows 10 motorcar. The Arduino I've used is the UNO WiFi Rev two, though the steps (and problems I solved) should be similar for virtually Arduino models. Meet common problems at the bottom of this guide if you're having whatsoever issues following the steps. I've besides tended to apply sketch and code interchangeably in this guide, a symptom of being an electronics and software engineer by grooming.
Footstep 1: Connect Arduino using a USB Cablevision
Typically a USB Type-B cable is used to connect to an Arduino – information technology has the USB 2.0 Type-B connector on one end and the USB two.0 Type-A connector (for a computer on the other).
At the store, I asked for a "USB printer cable" as this is also the sort of cablevision that is used to connect a computer to a printer. It cost me a few dollars. Any standard length seems to be OK, though I imagine it must be shorter than 5 metres (xvi anxiety); I ended up buying a 1m cable.
Information technology didn't affair which USB socket I used on my figurer, they all seemed to work fine when communicating with the Arduino, even the USB Type-C hub that I utilise with my laptop allowed me to program the Arduino.
A separate power cable is non required; the USB connection to the computer will ability the board.

Footstep 2: Open up the Arduino IDE
The IDE (Integrated Development Environment) is used to write lawmaking, compile programs, and upload them to the Arduino for it to execute.
The IDE can be downloaded from Arduino'south website here. I used the portable one, so all I had to practise was excerpt information technology to a folder and run the executable. If installing it, follow the steps in the installation wizard to get started – I believe the installation sorcerer has the advantage of taking care of installing the drivers for you. It's the IDE that lets you write code into sketches, compile those sketches into instructions for the processor, and upload those instructions to the Arduino.
If using the portable IDE, yous might demand to install drivers (this is what I had to do, see "Problems I encountered" beneath). The easiest mode I institute to install drivers was to run the executable in the drivers binder where I extracted the executable to.
At offset my board wasn't listed, I had to click some text in the lesser left of the IDE to update it then that my board was shown. I was having a problem with uploading sketches until I clicked this update. Doing this update ran through the commuter install sorcerer besides (installing an additional driver), but I imagine it'southward a skilful thought to run through the wizard separately anyway (as I did above).
Stride 3: Select the Arduino Board and Port
Under the Tools carte at the top of the IDE, select your Board and your Port.
For Lath, I found that mine didn't show up at commencement, and the IDE had selected a like model. This caused me problems afterwards, so make certain your lath is selected. If your board isn't listed, check out the previous steps well-nigh installing drivers.
For Port, I found that the IDE automatically selected the correct port as in that location was merely one listed. Some of the research I did said that if at that place was more than one port, try each of them that'southward not COM1 (plainly Windows never allocates this to an Arduino).
If Port is greyed out it means that the IDE does non believe the Arduino is connected to the computer. Connect the Arduino and Port will become an pick that can be selected. If the Arduino is connected, it means the IDE cannot identify it, take a await at installing the drivers as per Step 2.
Step iv: Set up a Sketch (or write some code)
Starting with an case is the easiest way I've found of testing out a new Arduino and reckoner setup, or getting started on your ain projection.
To use an example sketch, click File then Examples so Basics and I like to showtime with the glimmer example. This volition load a new sketch that contains code to blink the LED on your board. These examples are already configured for your lath so it should glimmer the correct LED without whatever demand to modify the code.
Fifty-fifty when starting my own projection, I like to utilise ane of these examples every bit a starting point. It's lawmaking and a setup that you know works, which is a skillful identify to beginning. I then add to the code to reach whatever I'yard trying to do.
Arduino lawmaking, independent in a sketch, is separated into two sections: A setup, that's run in one case when the board powers up (or programming has finished); and a loop that runs in a loop equally long equally there is power to the lath. At that place are other ways that code can be executed (I'm thinking interrupts here), just that'due south another commodity's worth of item.
Step 5: Upload Sketch (look for the Tx and Rx LEDs flashing)
To get the code running on the Arduino, click Sketch then Upload. The upload step volition also practice the verify/compile step, so there's no demand to click it separately for the purposes of this guide.
The RX and TX LEDs should flicker a petty as the IDE sends the code to the lath.
I found that as soon as uploading the code was consummate, the Arduino started to execute information technology. This took me a while to realise every bit the default sketch loaded on my Arduino (UNO WiFi Rev two) was the Blink one where the LED blinked every 2d. To test this, I modified the code to flash unevenly (try changing the delay(xx) numbers) so that it was obvious my code was running on the lath.
If your code is not running on the board, bank check out the section below where I go through some of the issues I encountered.
Finishing Upwardly
Afterwards following these steps, you should at present accept:
- An Arduino connected to your computer
- An IDE that uploads code/sketches from your computer to your Arduino
- An Arduino that executes the code that was uploaded to it
If you're Arduino is non running the uploaded lawmaking, there could be a few things that went wrong. I've included below how I solved some of the problems I faced when uploading my first sketch to an Arduino.
Common Problems when Uploading Arduino Lawmaking
If you demand help with writing the code for a sketch, I wrote a whole guide on the basics of an Arduino sketch and how to use variables, equations, loops, functions, and more. Check information technology out here: chipwired.com/arduino-programming-linguistic communication-guide
These are the problems I establish when I was trying to write my first program to an Arduino:
My Board Wasn't Listed in the IDE
Under the Tools menu yous tin see which lath the IDE is intending to upload your program to. When I opened the IDE for the get-go fourth dimension, it automatically selected a board that was similar to mine just not exactly the aforementioned. I encountered problems uploading the sketch to the board because I had the wrong one selected; my board wasn't even an option!
To fix the problem where the target Arduino is not listed in the Tools bill of fare:
- Install the latest drivers from Arduino, these tin can exist plant in the drivers folder where the arduino.exe file is stored
- Install any updates for the IDE, look in the bottom left-hand corner when the IDE is first opened – it will alert you here if there are whatsoever necessary updates
Wrong COM Port or COM Port Greyed Out
Usually this is due to the wrong drivers being installed for the lath you're using.
If y'all've installed all the drivers and your lath is selected in the IDE (see above) but the COM Port still isn't right, I've heard that updating the drivers in the Windows Device Manager is the way to fix this
Programmer is not responding
When I first tried to upload a sketch to my Arduino an error popped upwardly saying something like avrguy: programmer is not responding.
From my experience in microcontroller electronics (I'1000 relatively new to Arduino), the Arduino that runs your code tin exist a separate board to the device that records the program to the Arduino (the 'programmer'). On my first Arduino (an UNO WiFi Rev 2), the programmer and the microprocessor are part of the same board. Other Arduinos might have different configurations – eastward.g. having a separate developer tin save space every bit it doesn't ever need to be fastened.
To gear up this trouble:
- Ensure the correct board is selected in the Tools carte of the IDE
- If there is an selection to select the Programmer (in the Tools menu), and so make certain the correct programmer is selected
- Ensure the correct drivers for your Arduino (and developer if split) are installed on your computer – come across the steps higher up on how to do this
Later on many years away from electronics projects, Chris recently dived back in by picking upwardly an Arduino. This guide was written based on his start experiences setting up a computer to program an Arduino.
