In this section, we'll learn how to use the analog pins to read inputs and control outputs.

There's thousands of arduino tutorials on the internet, but the pacing, clarity, and thoroughness of your presentation make you stand out. I've methodically been watching this series from the first video, and following along with my own arduino, and I've been learning SO MUCH. Thank you for all the time and effort you've put into creating these videos and giving them the world for FREE!
Mate, your tutorials are bloody brilliant!
Man this playlist has helped me so much with understanding Arduino
Brilliant. I only wish I'd found your channel sooner in my hobby career.
Excellent information, articulately gone over. thank you.
thank you, your video helped a lot!
For the last circuit, the one with the led light, could we have used analogWrite instead of digitalWrite and not used a resistor
analogWrite is not truly analog. Rather, it is Pulse Width Modulation. While the average voltage is variable, the pin is only ever fully on or fully off. That means you will have a *lot* of current being pulsed through the LED which is bad for both the LED and the Arduino.
Feel free to open a thread on our forum if that doesn't clear things up: forum.core-electronics.com.au/
Nice subtle PWM arps going on in the background music track!!
...nice catch at 9:58!!
Refreshing
Excellent... thank you
Enjoyed your class, but some jagoff was sitting behind me playing Nintendo DS under his desk the whole time.
Sir May i Ask, I'm just a little bit curious about how did you determine the outputs 0 to 255 range of 8 bits?, is there some truth table or something. I'm not really familiar with this so i'm curious bout anything, hope you understand. thank you.
2^8 is 256 , in binary you'll have 0000000(zero) - 11111111(255)
Good video especially the fact that while analog in can be 1024 but analog out via pwm is 8 bits I. E 256 levels.
But u Registered an int function for PotVal ===== which means that it can only register as an integer But sometimes the analog read from the potpin will not be divisible to 4 so.... I think u should have used a float function . that will make them more smoother ig , am i right or wrong? pls tell me
Interesting
Can we take out analog output from A1 pin for LED?
Plz make tutorial on ARM.....🙏🙏🙏
I don’t like your description of a potentiometer an how it works. There is only ONE resistor between pins 1 & 3, whilst pin 2 is the “wiper” and it “sweeps” across the resistor tapping off the varying potential (hence Potentiometer)

@@seanmooney1391 lmao dude we are trying to learn here. you should have been thankful to him
hi i have a 25 yr old cnc machine that im trying to replace orig controller board with arduino and control that way...im using orig 25yr old stepper driver board.....i .i have used a mach3 breakout board and machine stepper motors responds fine but when i try using arduino uno as controller i get no response from the stepper motors...the stepper motors engage when pc and arduino uno is powered on but they dont respond to any jog moves in UGS.....i use Universal gcode sender and all looks good.....is arduino signals possibly not compatible with the 25yr old stepper driver board?
18:30 why do you do analogWrite on ledPin when the ledPin is a digital pin? can someone explain it to me? thanks.
nevermind. it has a PWM pin hahahahah did not pay attention.
tnx..
My sketch say 'App was not declared in this scope
Exit status
awesome ..

ok good vidio british dude gguy
bg music disturbs alot
He sucks at drawing as much as i do. I couldn't draw to save my life. lol
