Hello, i am new to making electronic circuits... I made a 12v pwm led strip dimmer using 555 timer and when i turn it on the led strip only lights up like 40% of its brightness so i am asking for some help.
Or the FET isn't been switched properly?, there seems little in the way of a driving circuit and it may be working more as a linear device than a switching one?. A scope would be useful, for checking what's coming out the chip, and what's on the drain of the FET.
I'd suggest not going below about 33 Ohms, as a power MOSFET may have very large gate capacitance & cause current spikes without some level of limiting.
