Brilliant work....thanx for everything.

Brother can you please upload how to assemble the Arduino and other on that board please it's a humble request i have to make it for maths exhibition

Thanks, explained very well

Hello, by chance, don't you have a code in the Arduino IDE to adjust the firing angle of a three-phase controlled rectifier (SCR) circuit?

very well explained with diagrams.

is it good to direct connect arduino to SSR ? for safety any circuit? // actually i have teensy4.1 controller which o/p when logic high is 3.299 volt , and my ssr input range is 3-32 v dc . and max current for this controller is 4mA any safety circuit or directly connect to this board an ssr is ok?

ac input is 220V or 12V ?

Very nice❤

Can i share my circuit diagram for another printer, and till me if it will work with yours or not?

Instead of optocuplor using to detect ZC. Diveder resistor can be used and tied to an analog pin to detect ZC

superb video! learned alot!! thank you TECHOOL Lab!

Hi bro, how do I hook it to 9v power adaptor and to Arduino?

Hi bro, can I ask for the library?

Sorry can you make this dimmer automatic, eliminating the use of potentiometer?

Thank You

which battery you use for power supply?

How come this video doesnt have any viewers and comments....i think it is a genius way of implementation...

Very best project sir how to control generator Help of Arduino please make this type video

Don't forget a snubber circuit for inductive loads. Got to do something with back feed current on stop....or pop!💕

The haa1 optocoupler needs no bridge only a resistor for crossover....cheaper and easier.❤️

this video is from 2 years ago, my circuit of the mouse I have is different and also is there any way to make it more comfortable? , I'm making this pen because I want to play this game called osu and it kinda relays on a stylus pen or a mouse for that matter.

Can we print hindi text using this printer how can i print hindi text

Please explain for 248 262 volts

so i need a welding machine?

Please tell me, it appears in the opening video that you can use Blynk APP to control the AC Bulb with Arduino AC dimmer.😶

It doesn’t work

How to connect ttl thermal printer to a laptop

Can you explain why the leds alternate?

Sir I am trying to print bitmap images on it but it is not printing please make a video on this topic as well

Hii brother very nice project.... ❤ Can you help me ....?

Could you add BOM and P&P file please?

Sir what is the model of thermal printer?

I have a wireless mouse Also can I use without buttons

sir what if i only connect live wire to dimmer and the gnd to the load does it will work fine or not

Hey there, i am looking to make a mouse pen and try to track the patterns of 2d shapes, do you think that is possible or should i use photogrammetry for this ?

Hi friend.. how can i connect it to a vending machine to print a reciept?

Great stuff...

Sir, I have run the code in esp8266 but its showing error of "ISR not in IRAM". Could you please help me out with this problem

Yg di jelaskan type berapa utk arduinonya,tks

Can you please help me with the connection and arduino code for 16 ch multiplexer with esp8266 nodemcu and ir sensor?

Você poderia fornecer o código-fonte do arquivo?

there are a lot of parts

I am taking my words back

YOU ARE THE BEST TEACHER FOR STUDENTS

hi there. i would like to have a a3 size thermal printer. where can i get items for a3 size thermal printer?

What do you think the total cost would be to make this?

I connected arduino out pin to MOC 3021. But the MOC not operated. The voltage of arduino pin drop to 1 volt. How to solve this?

CAN NOT OPEN LINK GIVEN FOR GERBER AND CODE

Its help to improve my zerocrossing knowledge Thank u🎉
