  • The maximun output current for a 7420 is 10ma. It may not last long driving those LEDS

  • can i eat danka please?

  • Does the 7 seg display work?

  • Ha it works. I think I got it that day and was just wondering what it looked like. This circuit does not utilize the 7 segment display. If you look at my other videos I have one of the 4026 7 segment display driver.

  • Really Cool vid! Definitely subbing!

  • Woah....thanks man.
