RGB LED Array Control Using STM32 Multiple ADC Channels With DMA

[@veisystems267]

@1:17 Just an FYI, that is not called a "DIP" package, but just a "through hole radial" package. DIP packages are Dual Inline Packages which are 2 rows of pins (like ICs or resistor arrays, etc).

Thank you for the correction

Woroooood hope you are doing fine and healthy!

Shamloon I miss you ma bro

When wiring LED's in Parallel each should have it's own resistor.

Nice work 👍

[@mertcelik236]

Good job, thanks bro 👍

[@usefulelectronics]

Thank you too

Enybody know why smt32 uCs double in price on Aliexpress?

[@usefulelectronics]

There is a worldwide semiconductor production crisis in Taiwan because of water shortage

@@usefulelectronics Thank you

Nice video, but electronic design is wrong. You should use NPN transistors as low side switches not PNP.

[@usefulelectronics]

Hi, I used PNP transistor to avoid inverse logic at the output. Using PNP is not the issue. The problem is the used LED parallel configuration. A combination of series and parallel LEDs would guarantee better current distribution Thank you for your feedback

[@PLGonzoG]

@@usefulelectronics there is no inverse logic with NPN transistor. HIGH on MCU pin turns on NPN transistor. Also you don't need base-emiter resistor to keep it off when there is no signal.

[@usefulelectronics]

@@PLGonzoG yes You are right. I have checked the BJT I used and it is 2N5551 which is an NPN actually. I demonstrated the BJT I am using at 4:02 I will correct the schematic. Thank you
