Your videos are awesome. I just started working with Arduinos and I am learning a lot from you. Thanks

[glenmerwyn]

Another great video / tutorial. You're awesome ! Cheers (I'm an engineer, with 20 years experience, trying to pick up electronics; your channel is probably the best, on YouTube, for electronics.) Cheers

I really appreciate your tutorials, I just started learning Arduino and I discovered your YouTube channel. Good work. Thank you so much!

Great stuff. I hope more people find this series. I have been looking for projects for my kids and you have done a great job explaining the topic in each of your videos. Plus you're not even a native English speaker so even more kudos!

Thank you for your educational videos. Your vidios Will help to projects

Thanks for the helpful video! Just wanted to let you know about an error in the schematic on your website: the button and LED are shown going to the positive, not the ground. Still super helpful, thanks!

Great help thanks. Not many videos on serial monitor inputs.

thank you so much. just a question how we can send more than one character for example
send 0001

[charmindesai]

Can you explain the first two lines of the "void loop" at the time 3:50.
Well, have learnt a lot from your videos, thanking you.

Do you have a video tutorial highlighting how to address more than one device sharing the I2C port ?

HI! Do you know how to show the waveform of speech recognizer in Serial Plotter? I have an app that I made in mit app and I used it as an speech recognizer. Then, it is connected to the arduino so that I can use voice to light up leds. But I need to show a waveform in the serial plotter.

[hakemass]

please do you have an idea how to do this using Atmel studio rather than arduino sofware ? 
Thanks in advance

Hello!! I have one question for you so. Can I make a serial communication through the pc and arduino with a bluetooth module?? I mean conect the PC with a Arduino who have a bluetooth module . I only turn on the Pc's bluetooth.

Great tutorials. If I want send sensor data from Mega2560 to ESP8266 by serial, How can I use Serial communicate between Mega2560 and ESP8266? Does it possible? I want to store sensor data on Firebasse. Thank you.

nice video.
Everything works perfectly fine in the arduino uno but when I switch to my external power supply or connect it to my pc without the serial monitor open it doesn't work anymore. the program is already loaded but still it doesn't work. please reply me if anybody knows.

[hajarchatoui]

HELLO iwrite that program but not work on me i would not acess to write 0 or 1 for led
int led=13;
void setup()
{
pinMode(led, OUTPUT);
Serial.begin(9600);

}
void loop()
{
if ( Serial.available()>0)
{
char ledstatus=Serial.read();
if (ledstatus=='1')
{
digitalWrite(led, HIGH);
}
if (ledstatus=='0')
{
digitalWrite(led, LOW);
}
}
}
