Great!!!!! Thank you!!! Could you please tell me the power rating of the resistors?
Sarah
Principally only R3...
R3 = U / I, where U is the voltage across resistor R3 = 0.7 V, and I is the required current through the load in amperes.
R3 = 0.7V / 0.7A = 1 Ohm
W = 0.7V x 0.7A = 0.49W
I used 1W for R3, the others at a minimum...

Offtopic, I quickly put this together. Maybe someone can check it?
Amy
I added the wiring file for the Splan program to the header.
Michelle
soldered, works.. thank you.

Good evening! As far as I understand, you connected 3-4 diodes to each PWM? Could you tell me the maximum allowable voltage for the board? Thank you.

I wonder if it is possible to connect a circuit with a photoresistor to it, so that the lighting would be adjusted throughout the day based on it. Naturally, setting the upper and lower thresholds. Thank you.

I think it's no problem. Instead of a rheostat, we put a photoresistor and a relay.

Add an additional capacitor of 0.1-0.5μF at the input of the driver; it will allow brightness adjustment from zero... (I have a 50k variable resistor - corrected in the header...)
1982, If you power the NE555 with 5-12V separately, the driver’s power supply is limited by the maximum parameters of the field transistor.. (STP60NF06 N-CHANNEL 60V 0.014 OHM 60A TO-220 STRIPFET POWER MOSFET)

Question... why such a powerful transistor? They cost 15... maybe something cheaper can be used, not for 60A but smaller. I am a beginner in circuit design.
Adam
Anyone can, I used what was available...

Good afternoon. Can it regulate three three-watt LEDs? Where do I solder the diodes? I don't understand anything.
Joseph
Well, of course... look at the diagram... 3 pieces. The Krii pulls without any problems.
