Compile and Upload the Code on the Arduino
Equally an electronics engineer getting back to my roots with Arduino, I institute information technology could exist a lilliputian confusing getting started uploading code (or sketches) to an Arduino. Installing drivers, IDEs, and everything else involved wasn't a straightforward task. Then I put this guide together based on my experience uploading code to a new Arduino on a new calculator.
This guide is a pace-by-pace (with pictures) on how to upload and run lawmaking on an Arduino using a Windows 10 machine. The Arduino I've used is the UNO WiFi Rev 2, though the steps (and problems I solved) should be like for most Arduino models. See mutual problems at the bottom of this guide if you're having any problems following the steps. I've too tended to use sketch and lawmaking interchangeably in this guide, a symptom of being an electronics and software engineer by preparation.
Stride 1: Connect Arduino using a USB Cable
Typically a USB Type-B cable is used to connect to an Arduino – it 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 cablevision" equally this is also the sort of cable that is used to connect a computer to a printer. It price me a few dollars. Whatsoever standard length seems to be OK, though I imagine it must be shorter than v metres (16 anxiety); I ended up buying a 1m cable.
Information technology didn't matter which USB socket I used on my computer, they all seemed to piece of work fine when communicating with the Arduino, even the USB Type-C hub that I use with my laptop allowed me to programme the Arduino.
A separate power cable is not required; the USB connection to the computer will power the board.
Need more help with which USB cable to employ, or which wires and cables an Arduino requires? I wrote a whole guide on USB cables and wires useful for Arduino, check it out here: chipwired.com/arduino-cables-and-wires
Step ii: Open the Arduino IDE
The IDE (Integrated Development Environment) is used to write code, compile programs, and upload them to the Arduino for it to execute.
The IDE tin can be downloaded from Arduino's website here. I used the portable one, so all I had to practice was extract it to a folder and run the executable. If installing information technology, follow the steps in the installation wizard to get started – I believe the installation wizard has the advantage of taking intendance of installing the drivers for you. Information technology's the IDE that lets y'all write code into sketches, compile those sketches into instructions for the processor, and upload those instructions to the Arduino.
If using the portable IDE, you might demand to install drivers (this is what I had to do, run into "Problems I encountered" below). The easiest way I constitute to install drivers was to run the executable in the drivers binder where I extracted the executable to.
At first my lath wasn't listed, I had to click some text in the lesser left of the IDE to update information technology then that my board was shown. I was having a trouble with uploading sketches until I clicked this update. Doing this update ran through the driver install sorcerer every bit well (installing an additional commuter), but I imagine it'southward a good thought to run through the sorcerer separately anyway (as I did higher up).
Step iii: Select the Arduino Board and Port
Under the Tools carte du jour at the pinnacle of the IDE, select your Board and your Port.
For Board, I found that mine didn't show up at starting time, and the IDE had selected a similar model. This caused me problems subsequently, so brand certain your board is selected. If your board isn't listed, check out the previous steps most installing drivers.
For Port, I found that the IDE automatically selected the right port as at that place was only i listed. Some of the enquiry I did said that if at that place was more than i port, try each of them that's not COM1 (apparently Windows never allocates this to an Arduino).
If Port is greyed out it means that the IDE does not believe the Arduino is connected to the figurer. Connect the Arduino and Port volition get an pick that can be selected. If the Arduino is connected, it means the IDE cannot identify it, take a wait at installing the drivers as per Step ii.
Stride 4: Prepare a Sketch (or write some code)
Starting with an example is the easiest way I've found of testing out a new Arduino and reckoner setup, or getting started on your own project.
To use an case sketch, click File then Examples so Basics and I like to showtime with the glimmer instance. This volition load a new sketch that contains lawmaking to glimmer the LED on your board. These examples are already configured for your board so information technology should glimmer the correct LED without any need to alter the code.
Fifty-fifty when starting my own project, I like to utilise one of these examples every bit a starting point. Information technology's code and a setup that y'all know works, which is a good place to get-go. I then add to the code to accomplish whatsoever I'm trying to practice.
Arduino code, independent in a sketch, is separated into 2 sections: A setup, that's run once when the board powers upwardly (or programming has finished); and a loop that runs in a loop as long as in that location is ability to the board. There are other ways that code can exist executed (I'm thinking interrupts here), simply that'due south another article'southward worth of detail.
Stride 5: Upload Sketch (look for the Tx and Rx LEDs flashing)
To get the code running on the Arduino, click Sketch and so Upload. The upload pace will also do the verify/compile stride, so there's no demand to click it separately for the purposes of this guide.
The RX and TX LEDs should flicker a little as the IDE sends the code to the lath.
I institute that every bit presently every bit uploading the code was consummate, the Arduino started to execute it. This took me a while to realise every bit the default sketch loaded on my Arduino (UNO WiFi Rev 2) was the Blink one where the LED blinked every second. To test this, I modified the code to wink unevenly (try changing the delay(xx) numbers) so that information technology was obvious my lawmaking was running on the board.
If your code is non running on the board, check out the section below where I go through some of the problems I encountered.
Finishing Upward
After post-obit these steps, you should now take:
- An Arduino connected to your computer
- An IDE that uploads code/sketches from your computer to your Arduino
- An Arduino that executes the lawmaking that was uploaded to it
If yous're Arduino is non running the uploaded code, at that place could exist 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 Code
If y'all need assistance 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. Cheque information technology out hither: chipwired.com/arduino-programming-language-guide
These are the problems I plant when I was trying to write my first program to an Arduino:
My Board Wasn't Listed in the IDE
Under the Tools menu you can encounter which lath the IDE is intending to upload your program to. When I opened the IDE for the first time, it automatically selected a lath that was similar to mine just not exactly the same. I encountered issues uploading the sketch to the board considering I had the wrong i selected; my lath wasn't even an choice!
To set up the problem where the target Arduino is non listed in the Tools menu:
- Install the latest drivers from Arduino, these can be found in the drivers folder where the arduino.exe file is stored
- Install any updates for the IDE, expect in the bottom left-hand corner when the IDE is first opened – it will alert you here if in that location are whatever necessary updates
Wrong COM Port or COM Port Greyed Out
Commonly this is due to the wrong drivers existence installed for the board you're using.
If you've installed all the drivers and your board is selected in the IDE (meet above) but the COM Port nonetheless isn't right, I've heard that updating the drivers in the Windows Device Manager is the way to fix this
Developer is not responding
When I outset tried to upload a sketch to my Arduino an error popped upwards maxim something like avrguy: developer is not responding.
From my feel in microcontroller electronics (I'grand relatively new to Arduino), the Arduino that runs your code can be a separate board to the device that records the plan to the Arduino (the 'programmer'). On my get-go Arduino (an UNO WiFi Rev 2), the programmer and the microprocessor are part of the same board. Other Arduinos might have dissimilar configurations – e.g. having a dissever developer can save space equally information technology doesn't always need to be attached.
To fix this problem:
- Ensure the correct board is selected in the Tools carte du jour of the IDE
- If there is an option to select the Programmer (in the Tools menu), and then brand sure the correct programmer is selected
- Ensure the correct drivers for your Arduino (and developer if carve up) are installed on your computer – run into the steps above on how to do this
Afterward many years abroad from electronics projects, Chris recently dived back in by picking up an Arduino. This guide was written based on his first experiences setting up a computer to plan an Arduino.
