The raspberry pico is anmazing but there just arent enough tutorials online for newbies!, this video was very helpful thanks!

[@hillsideheathen5267]

This was very helpful. I was able to have a 5inch touch screen AND have a fan connected to GPIO 12 for my 5" "Pocket Laptop" build. Thank you!

[@htkinfo9647]

Thank you for this wonderful tutorial. It worked like a charm. The only mistake I did was to have a high value resistor I used 220 ohm and it worked like a charm.

[@magiconverse]

This is awesome. first step in my project!

[@harpermartin7813]

God believes in you more than you believe in yourself!❤️🙏

[@rauljg143]

worked like a charm first try, thank you!

[@devnull6076]

Great video! Worked immediately :D

Of course ❤

Hello. It's such a great video, and in the end a doubt came up. I'm doing a school project that consists in a smart house with Raspberry Pi 3. I want to connect multiple leds to the house. What are the pins that i am supposed to connect the jumpers? And it's necessary to use a protoboard for do that, or I just have to weld the jumper to the resistor and the resistor to the led?

[@254_Cyrus]

How did this turn out?

[@CharlotteSimmons1]

So you switch over to typing commands straight away, so Raspberry Pi must be on while you do the wiring?

If I clipped an LED to get a board out of something, but want to reuse that LED is there any way to know what side is positive?

[@ArshadAli-xk5pk]

Sir ,if we attached mean here using led but if instead of led if we use dc fan then the code will just like we will use for led or for the fan we will use another code ?

[@avimartinez4000]

hey can i ask something? what if i want to give an output signal through the raspi's pin but i want it between the minimum and maximum range (ex: pinout = 1.5 volt from 0-3 volt scale), can i configure the python code into percentage just like in arduino?

[@droneverse1203]

No

[@DamianLuettig]

very useful, thanks!

[@antomicawad6377]

Can i connect ground and the gpio facing each other?

[@martincregg]

I think a 470 ohm resistor will not provide a enough voltage to the LEDs. I needed to use 220 ohm.

[@prabhacar]

very cool! thanks

[@christopherlong3397]

Very Helpful 10/10

[@3inores579]

what ohms the resistor?

[@lucionieto4020]

You can calculate that with a formula, but usually is 220 or 330 ohms. Good luck.

[@skinnyfishin2357]

220 r

Actually, if the idea is to protect de raspberry, the resistor should be placed between the ground end the LED... not between the GPIO end the LED...

[@nickisacebeans]

I don't think it makes any difference because it's in series.

[@chrystal1062]

@@nickisacebeans Correct. Clearly, Joan has no idea how circuits work.

[@RSuarez66]

How about if I would like to control a traffic light circuit (4 X 1red, 1grn, 1yel)? I am a beginner in programming.

[@sirionero344]

Can anyone explain to me why we should use the resistor, I really can't understand why. I would be very grateful

[@clarkdriscoll3540]

It's to prevent the LED from burning out too quickly. Inside each LED is a chemical that when electrons are passed through, it glows. The more electrons or the higher the current flowing the brighter it will glow. So why do you need a resistor in series with your LED? Because nothing is limiting current flow! It can fry without one.

[@sirionero344]

@@clarkdriscoll3540 thank you very much you helped me a lot

[@mylodefaut-juneja3705]

Hi Can anyone help me please. When I type in import RPi.GPIO as GPIO I am told "No module named RPi.GPIO" Do you know what I am doing wrong? Many thanks

[@treudden]

It worked!

hey can i do this with rpi 3 b+ ?

Yes, of course You can : )

It doesn’t work wtf I’ve tried everything someone please help

lol

EZCLAP03 it works now

[@ezclap0379]

Good to hear man

[@larisapopa9556]

I LOVE YOU

[@marinatuffier6664]

if it already three volts the average Light emitting diode can with-stand it so what's the point of adding a resistor

[@adabrew2310]

Better safe than sorry,

[@Rainbow__cookie]

You can use even 5v if you have a resistor

[@robasscakes5061]

He literally said it's about damaging the GPIO ports. If you have too much current draw from the GPIO port then you could break it.

[@pazuzu810]

This man looks so unexcited. I hope everything's alright.

[@connerdassen7808]

Please don't call this a cookbook with recipe's. It sounds so stupid

[@fredhair]

It's called a raspberry pi.. it already sounds stupid at least a cookbook fits the theme

[@vighneshchavan9226]

Bruh... 🤣

What the hell it didn't work
