5 tips to optimize your arduino breadboard projects

Can you try to dim out the LEDs in post? They were pretty blinding when I watched on the TV.

I do normally. But in this video I could not. As when talking about lilypad led I was powering it from 5v power supply directly so did not have mechanism to dim it and for 8x8 led matrix the purpose was to show it be the brightest. I noticed it is a problem and in recent videos whenever I was controling led with arduino I used analogWrite command and used PWM feature to dim leds. You can see it e.g when you watch my video about controlling 12v devices with relay th-cam.com/video/XiOcxyyTxy4/w-d-xo.html where I did not dim the light and I was struggling to film it and then in the next video I fixed it

@@marios_ideas Ah, alright, thanks!

Is the pullup resistor available in all pins or just pin 9?

[@marios_ideas]

I think all the digital pins accept Digital pin 13. D13 also has the pullup resistor but this pin also has on board LED attached and it is recommanded not to use INPUT_PULLUP with this one
