Now, I am following the Arduino R3 tutorials, but I came here to tell you that you are the best teacher I have ever seen

Wow, thanks!

Most programs need to use if statements and conditionals, so this is another important lesson!

3 words: Amazing Amazing Amazing I Really learned from you Mr. Paul, and I would love if you made serial videos about ESP32 using MicroPython or arduino, or both Thank you

2 tips: 1. clear monitor window before each run. 2. include a print to show what number you entered, hard to see on the line where you enter the value and goes by quick. Nice work.

Hi Mr McWhorter, Do you can help me with a Bluetooth Module HC05, to set Role Master? I cannot change the role, please help me

You might want to indent - Conditional statements, while, for statements to give your code some formating. You will find it easier to read

Sir when will you have to make videos on how to use the esp32

I've used if else during this tutorial, instead several if conditions

i lost the meaning of "Serial.parse", what is "Parse" standing for?

@robertschuldenfrei2402 8 ай бұрын

Parse means to split apart. You could split out an integer from a string by writing a program to look at the string character by character. You would be looking at each character to see if it was a number. You would have to be mindful of the minus sign. Years ago, 1968 to be exact, I did just that with the original Dartmouth BASIC.

My Homework kzbin.info/www/bejne/a2PVoJeApM5qm6Msi=f_djVs8j0s2FAlNb I tried to set up the code so any input other than red, yellow and green would turn off the LEds and give a message like "there is no such LED", like: if (colInput !="red" || colInput !="green" || colInput !="yellow"){ digitalWrite(rPin,LOW); digitalWrite(gPin,LOW); digitalWrite(yPin,LOW); Serial.print("there is no such LED"); } But this doesn't work. Any suggestions?

Thank You Robert! Yes, this worked but I still don't understand the logic behind it.@@robertschuldenfrei2402

@robertschuldenfrei2402 8 ай бұрын

@@richardsstark9825 Here is the logic behind it. In the || (or) construction if the color you entered is "red" it fails the first test since the color IS red, but it passes the second test because red is not "green." Even if the red LED was turn on in an earlier test like if(colInput="red") it will be turned off immediately when it hits your "or" constructed statement. If you want to learn Arduino programming at a much deeper level than Paul can do in this course I recommend a very elementary book: Sams Teach Yourself Arduino Programming in 24 Hours by Richard Blum. Even if you have never written a program before you could learn how it is done with this book. You will come to understand why some function look like loop() and others look like myValue.toInt(). [answer: the first is a function and the second is string object method]

wikipedia... One 0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. 🤞 Twilight zone stuff.

My ArduinoR4 homework 16 kzbin.info/www/bejne/eYjLl6uOebVpqZo. Thanks Paul. I used a blinkLED function. Paul has recently gone over functions classes and methods in the PicoW series approximately lesson 64. I thought it would be a challenge to see if I could do it in the Arduino IDE.
