And if we use ds18b20 sensors?

If I vary the dc voltage output voltage also vary

Thank you for this informative video, and the link..I am a hobbyist on a budget, and this is perfect for experimentation.

Eu vou montar com o lm 338 pq comprei um mppt azul e é uma bosta pra carregar minhas baterias não sei se veio com defeito!!! Mas vou montar esse com lm 338 e vamos ver se vai dar certo!!!! Vlw

I want this to work. But it doesn't work.

Whats transformer characteristic? Thx!

very good mate, i will try it out on my flashlight.

Can this be used for just one motor… that reverses?

if i want the fan to start at 60 oC i need to control the potentiometer right?

thank you for making a video on this topic. I had lot of trouble ever since I changed my old florescent tube light with a LED light. LED light bulb emits too much light and it badly effects the water by aiding in algae formation. I will use this technique and post my next comments on how it worked out for me.

Give me code I need to count people who enter for a project and my prof wasent very helpful

You didn't use potentiometer in this? I want knight rider effect with potentiometer really quick.... Please help me

link to this relay?

Thank You, it answered my questions, so I can apply this to a much larger NC Relay for a project I’m working on

Does it really work on a dog

How to contact you?

Hello.. is that 9-0-9 trafo?

Thanks for the video man, do you remember where you got this NC relay?

haii, do you have this circuit schematic diagrams ?

What's the voltage of the fan?

How much resister value battery discharge use

Please provide me schematics please or circuit diagram . The link you provided is not working

if i use a 20khz(sinewave) into a piewzo tweeter at 10W will that work too?

what kinda waveform is that?

What is your PCB thickness? Did you modify the height of the rollers for the PCB thickness 1.6mm?

u're the best dude , thenk you sooooo much <3<3<3<3

I don't have camera bliț pls help me

NOT WORKING!!!!

vc e brasileiro nao?

Thanks for this Informative video

Whats the maximum delay I can put in? For example..I want to use a switch to turn a relay on...if the switch is forgotten and left on, I want the relay to turn off after a few hours of it being on. Do I need an external clock for this or will the Arduino do it provided it is on and programmed for the time? Consequently, when the switch it turned off, it resets the timer until the switch it turned on again to perform a function... Much like how newer cars will automatically turn off the interior light after X amount of time if you accidentally leave it on.

47 C? GO TO DOCTOR ASAP

He is using yellow toner transfer paper you can get it on Ebay and on Amazon as well

There is an error (#include expects «filename »

interesting! can this build a dry cabinet with large fan? or need few DHT22 humidity to put in all the location that need reduce humidity...

do i have to use a Transistor to controle the fan with the potentiometer ?

What is the code

Can you show the circuit desgin equation, Sir?

Thx, this is exactly what I need to prevent a button from acting as a resetbutton when power is applied to the device. When device is standby, then I can use standby power to wake device.

your project is missing a version for a cheaper Arduino nano, would be great if readings are displayed also with a schematic drawing

But if it is at 24khz why does it not jam the microphone of your camera?

it is really wrong . it is normally closed . NC .

I went through the video and the article which was very useful to me. I wish if you can guide me to incorporate a LCD display in the code and a relay driver to drive a table fan it will be more useful to me to try out. I am eagerly awaiting your help in this respect.What are the additional codes needed in this sketch and also the circuit to incorporate. Thanks for the project which enlightened me about Arduino.

This might work for a solar system. When batteries are down switch from the wall and if fast enough could also be used as a ups inverter to run uninterrupted power. I think they sell fancy inverters that switch from solar system to main and you dont even notice a glich in the power but they cost over 500 dollars. With this you could wire the wall and a battery in an emergency!

Can you assist me to do this with a 24V fan? I have high temp turn off already to turn off the system, but no speed control for the fan.

laking tulong, salamat :)

Thanks for parting this video and the code which was long waited by me to adopt in my small green house in the kitchen garden.

Sir send immediately
