Hi community,
after some issues i was able to finish my heatermeter. At the beginning it thought everything works as intended, the HM display went on, i was able to configure everything but after some testing i have the following problem.
The fan doesnt spin when i connect it to ground + blow. (it spins when i use the 5V or 12v at the power input, so the fan is functional).
The HM was in manual mode at 100% all the time and i changed the fan from voltage to pulse mode.
I did some furhter testing, the last point where i m able to get 12V is the left leg of the mosfet. If i connect the fan to the middle leg, the fan wont move. (see next post for better informations)
I would be pretty happy if someone could help me, i dont know much about smc soldering or electronics, this was my first project.
I could do further tests with a mulitmeter if you give me advices how to do it. (i know how to use a multimeter, but i dont have a clue where to use it )
Sometimes i have a second problem. After i start the heatermeter it jump through the menu, it looks like someone would click on all buttons at the same time. Some ideas?
Thank you and greetings from germany.
