I built the cube and everything but I'm stuck on soldering the mosfets. I followed the schematic but they don't work properly and/or i don't understand them. The orientation of your arrows in the mosfet schematic is different from the orientation on the datasheet. Also in your mosfet video, you say to use a 10k resistor.

Hi!
I have one thing in mind, which I don't understand. It is the part with the MOSFETs, the source should be connected to A1, A2 and so on, then linked through a 1K resistor to the gate? Which is Also connected to 5V of the arduino? Also where should I add the capacitors? Thanks a lot!

Hey. I collected the cube under the scheme but when he began to fill in the code in the Arduino my issues (ledcube. ino: 4: 200: fatal error: Tlc5940. h: No such file or directory
compilation terminated) Prompt where I made a mistake. Thank you.

dude not to complain but your Arduino schematic A0-A7 is reversed. so should we follow the numbers or the location where the schematic says to connect to on the Arduino? i. e. instead of connecting to A0-A3 should we connect to A7- A4?

Scott i love your videos very much, the best on YouTube. Can i please know why are capacitors used here and also can you tell me from where can i start learning electronics from intermediate level(any book you recomend? Thanks.

if your going to take all that time to solder the pin headers on and together a single sided pcb why didnt you just home etch a pcb with a laser printer with smd socket conectors like and IDE cable or somthing?

Hi Grate Scott I am making circuit now almost it's done but now I confused which wire goes where from IRF9540N. Symbols are bit confusing. Please tell me where G, D and S pin need to contact. Thanks in advance

Hi,
why do you use pull up resistors on the mosfets? The voltage which runs through these resistors should be very small. Is it to stabilize the voltage on the pin and to avoid floating? Thanks.

Hi, GreatScott, on the schematic, at 3: 13, on the RED IC, is VCC connected to DCPRG? Because it does not have the ball on the connection, Thank You, And like so much your videos!
