Electronic Basics #4: Arduino+Bluetooth+Android=Awesome
video description
I got a question that I think you could help me.
I have an Arduino project with the Fingerprint module. After i finished it, I want to register a new fingerprint to my project but I want to do it without connect it to the computer. But I want to register it through Android Application that I made using the MIT APP INVENTOR. After that I am confuse at how to write the Arduino code. So I really hope that you can help me to finish this project

Hi, I need to put a transmitter on the collar of my dog, so when he barks it would trigger a device in the house. I also need to keep track of the barks on an app on my phone that I will later make. What technology do you recommend? How? Thank you so much.

Realy nice, i started with arduino starter kit dezember 2018. And ich try to understand how to use arduino for smoller projects. Like your Video.
Can I use the colors in between of RGB Basic colors of is it Not possible with this code?

I saw some diagram show that you need 1k+2k to create divider. But in this video you use 4. 7k + 2k. Is there any difference?
Also function allpinslow) but it sets all to HIGH which is the opposite of the function's name.

4. 7k and 2k resistors would output 3. 5v but there's usually a loss in volts so it probably wouldn't destroy your bluetooth module. A 4. 3k and 2k resistor would output 3. 4v. A 4k and a 2k resistor would output 3. 3v.

could this be adaptable to a Digital Potentiometer function where instead of controlling whether the LED is on/off, it could send signals to tell the digipot whether to increase or decrease its resistance?
thanks

I live all your videos but as someone who starting to learn electronics its sometimes a bit complicated. Could you make some basics videos that start from the beginning like the real basics.

Hi! I tried to open the code in the Arduino IDE but I could not get it to open the. rar file. Can you please fix this as soon as you can? That would be awesome!
