I use my Arduino IDE to either upload my sketch to a Arduino or ATTiny or ATmega328. As you know each device can have a different pinout. Does the Arduino compiler support ifdef, depending on the b...
Ethernet Something like the Arduino Ethernet Shield allows you to plug in an Ethernet cable from the wall or router into your Arduino. Obviously, the main limitation is that your device is now tethered by the cable. For outdoor use, I wouldn't do this. WiFi The Arduino WiFi Shield allows you to connect to your home WiFi network.
I have been using the Arduino to record some data. In my Arduino sketch I also used the millis() function so I can keep track of the time at which each value I am measuring is taken. However, I not...
Say I have some variables that I want to print out to the terminal, what's the easiest way to print them in a string? Currently I do something like this: Serial.print("Var 1:");Serial.println(var...
When trying to upload the blink sketch to my (unofficial) Arduino Uno, I get the following error: avrdude ser_open () can't set com-state for "\\.\COM3" I have programmed this Arduino before using ...
I made an awesome program the other day, and I wanted to upload it to my Arduino. After clicking the upload button, some mean dude named avr came along and stopped me, saying: avrdude: stk500_get...
Plots several data on the same axes; Exports / Imports file data. As plotting serial data from Arduino is a common need, my question is: What programs/utilities are available for plotting serial data from Arduino that meet the needs above? What are the advantages / disadvantages of the method you have suggested?
Linux Getting Arduino and Arduino-like boards working properly under Linux can be a troublesome task if you are not familiar with how Linux works. So I am going to introduce you to some of the basic tools you will need to work out why your board isn’t working as you’d like it to work. The majority of problems a new user is faced with boil down to one simple thing: permissions. A normal ...
I'm new to Arduino/C development (coming from a JavaScript/Ruby environment), but I was wondering if it was possible to include a library from a custom folder within a sketch? So this is my situat...
