Find out how to write compact code with multiple conditions and how to reduce long lines of 'if-else' statement into short code. Get it right First Time.Arduino switch case: Is your long list of if-else C code getting hard to read?... ...If so, you need to use to switch-case ...
and go to the Tools > Board menu in the Arduino IDE, and select your board. Then in Tools > Port, select the right port. In Windows, this will probably be a COM port. If there are multiple ports available, unplug your Arduino, then plug it ...
if (n == 0) { Serial.println("no networks found"); } else { Serial.print(n); Serial.println(" networks found"); for (int i = 0; i < n; ++i) { // Print SSID and RSSI for each network found Serial.print(i + 1); Serial.print(": "); Serial.print(WiFi.SSID(i)); Seri...
Adding this statement in setup() will enable SafeString error messages. You should normally add this when developing your sketch and then remove it once your are finished. If you get any errors later your sketch won't reboot, the SafeStrings will just not contain the text that would not fi...
Reference Home if / else if/else allows greater control over the flow of code than the basic if statement by allowing multiple tests to be grouped together. For example an analog input could be tested and one action taken if the input was less than 500 and another action taken if the ...
An easy way to check to see if you have the file a sketch is looking for is to navigate to Sketch > Include Library from within the Arduino IDE. Then look for the name of that library. Whatever library the #include statement was calling for, you want to look through this big long li...
The following if statement, checks whether the button state isHIGH. If it is, it turns the LED on using thedigitalWrite()function that accepts as argument theledPin, and the stateHIGH. if(buttonState==HIGH){digitalWrite(ledPin,HIGH);} ...
In this Arduino Tutorial we will learn how to use the DS3231 Real Time Clock Module. The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automa
