As i understand, using ULN2803 for this case it's a bad idea? And you suggest using discrete MOSFETs, right? Now I tried to measure the temperature of the transistor array and it differs from the room temperature by only +2 degrees, with a load of two fans.
Hello friends,
i'm newbie in microelectronics, but it's very interesting for me :grin:
Best practice to learn something - work with real projects.
I want build Web Based PWM Controller (NodeMCU + ULN2803) for my home server room.
Requirements:
- web based PWM control
- temperature monitoring...
