Dude! Fantastic Video!!!! Thank you so much for making this and going in depth on how things are playing out in separate frames of time. This is so informational and an amazing style of teaching. I commend you greatly and cant wait to watch more.

Well done

Will this work still? I had a esp01 with some stuff running by blynk but that stopt working sending out email or notifications. So this can work. But some time did pass and is it still working or do i need to look for something different? Thz,

Sher'lock.

I actually have an LND-712 tube that im looking to start making into an arm bracer mounted geiger counter Is there any way to make this circuit more compact? Preferably to about the size of a CD V-750 for scale?

This explanation is just great. This is really how you learn stuff. Thanks a lot!

This also worked on the Fuser Unit of a Samsung printer! Cheers mate!

I made a little Arduino device for my daughter who lives on the other side of the country (in Seattle). I'd like to update her device without having to ship it here and back. Is there an easy way for me to do this? We both have Macs, but she's not technical. The current version of Arduino IDE (2.3.3) does not appear to use avrdude. At least it's not listed when I compile and upload.

how did you sense the door closing on your board?

Do Geiger counters produce more electricity than is put in? If they do would that not mean it is creating energy?

Thank you so much!

you just made it so easy 13 years ago

In ESP32, if you flash .hex instead of .bin file, will the procedure change? Do I change the address? Do I still need to flash the bootloader along with it or just the .Hex one? Or do I just need to change .bin to .hex in the program file an flash?

worked well for me using a esp32s3, thank you for the simple solution

still a great video after 8 years. i am learning to code a Attiny right now. i learned how to disable BOD by software and ADC in this video!

WOW what a comprehensive tutorial, 11 yrs later, still makes sense!

Very clear explanation, thanks.

Would you be able to control a dozen DC-motors using the TLC5940? If you connect it to for example some TIP120's?

Hai kevin iam sha from.Kerala India. I want contact u personally .pls reply

I just tried this on my bad thermostat, same part in video. Worked perfect. Thanks so much!!!

Yes that is exactly how to do a tutorial.....Tnx Kevin you're awesome my friend!!!!...the best on strings I've found so far!!!....

7 yrs later your video is still helping people. Thanks for posting this!

This is exactly what I've been looking for. Thank you for taking the time to share this valuable demo 💯👏

i know i wont get an answer but does anyone know how to make it boost to more like 4volts?

Thank you very much, nice example and explanation, I was able to backup the Factory Watchface from my Watchy 2.0

I came here to debug getting some GPS text to do what I want. Got stopped for a couple of days. This video info can probably get me going again.

Pero hay una forma más simple de hacer eso y es dibujando la figura excel te da los colores de cada pixel en formato RGB565 los copia en el ide de arduino poniendo UNSIGNED CONST CHAR[]={ } y luego solamente poner matrix.RGBbitmap(x,y,bitmap,color)y ya

One of the best tutorials I've seen for explaining SIPO (Serial In Parallel Out) shift registers. Thank you

I'm sure that you intend this to be helpful but I wouldn't go touching components with my bare hands. And hopefully there's a ESD defense at work here somewhere.

Interesting ... I wonder what the internal mechanism looks like 🤔 Thanks for wasting your weekend to benefit others 😊✌🇦🇺

did you try to shield your hall sensor from outside... magnetic material like a tin can or more effective with permalloy foil ?

I'm happy to see others share my interest! I've been working on similar projects, exploring ways to utilize capacitors in a more battery-like fashion. While they're fundamentally different components, I've achieved some promising results. In fact, I developed a formula for this purpose when I was just 14 years old. I understand it might be controversial, but I urge you not to be discouraged by the math in the video description. The video itself might not be for everyone, but the underlying mathematics is sound. Here's the idea: Why not take a look at the equations I present? If they align with your understanding, perhaps they could be helpful for your capacitor project as well! kzbin.info/www/bejne/h2ionpl-pNyKobcsi=nv0cwxwRTZmoLwz0 😊

Any thoughts what would be involved in writing an ESP32 application, that takes data from the uart, and passes it wirelessly either via bluetooth** (SPP) or via Wifi? For Wifi, I imagine the ESP32 could act as a web server (TCP) and display the RS232 data, but maybe there's also a UDP way to send data to a PC on the same network? I imagine, if the receiving application (mobile or PC) is written with the flutter framework, it could display the RS232 data with style! **I purchase some USB-bluetooth dongles (Feasycom BP102, HC-05/HC-06/CP2102 master modules, etc).. but none can connect to any android phone! For example, when a Samsung S5 tries to connect to one of the bluetooth dongles, it will stop blinking, but after a couple seconds, Android says 'Can't communicate with the FSC_BP102' or HC-05, or HC06, etc.

7:24 don't drive that pin low, set it to INPUT aka high impedance state. Datasheet specifically warns against setting GPIO pin to LOW if you are using it to power the LMT01, something about reverse-biasing damaging the sensor.

How long did it take to flash 1000 boards?

thank you so much :)))

Great work on char and string manipulations. Could you talk about indexOf , trim and using substring? Many thanks.

Is it possible to just install a flow meter which the esp can read? in the pipe after the actual meter

I have a IGT S2000 Double Diamonds 25 cent quarter machine from Balley 90's in storage with no way to hook up or plug in due to no electricity. When I moved it would light up but the reel would not spin. What are your thoughts on a fix? After watching your video I do remember when my husband was alive he fixed it and we ordered a board from e-Bay and everything worked and then we would shut off when not playing it and sometimes just kept it on. Do you think since it was just left on, it might have just drained the battery? I don't know how to find the back board on my machine. Maybe I should hire someone. If so, how do I find a slot machine tech?

Amazing! This worked perfectly for me. You just saved me $34! Thank you :)

Exactly what I was looking for, thank you!

Just tested my Arduino Uno-compatible. Not a real ATMEGA328, it seems, but then it was only £7.27 incl. P&P!

Brilliant presentation. Strings get me every time I come back to coding in C/C++. Your tutorial is really helpful. Thanks!

I was wanting to know how the bug actually gets zapped and your video answered that! Bug has to touch both outer and the inner screens at the same time. Glad you showed how to safely test that by (safely) shorting it to produce the spark.

Thank you!

very great

Spent the whole day tearing apart and cleaning the dryer. The last thing on the list was to replace this suckered since it didn't have a switch. Well ladies and gents, not anymore.

Excellent Project for those who saw serial memory as mystical chips. (Sorry it took me 10 years to see this video)

It was much easier to work with Parallel Static Rams, in non-microprocessor based applications , however most such memories are now obsolete and not manufactured like the 6116 a 16K static memory, set as 2K x 8 bit RAM. So using serial Ic2 memories you do need a microprocessor to feed instructions into it, it is a sequential information into the serial memory chip, by sequential I mean start bit followed by chip select bit, followed by whether you want it to read or write to it, then entering upper memory bits and then lower memory bits for the address, then followed by the actuall 8 bit data, and finally a stop bit, a very tedious process, all just to save space and number of pins, and wide data and address lines on a PCB, all to do with miniaturisation off things, each time it steps through its sequence an acknowledge bit is send back to the processor, so it knows how the chip is doing, So basically serial memory is still configured as parallel internally except the chip has built in seral to parallel and parallel to serial decoder, so only requires a fewer pins, this was done to reduce the foot print, so its speed is compromised due to serial loading and serial reading of data.,
