@mehmet.bkr5: No More Overflow! ULN2003 Water Level Circuit I built a super cheap and highly efficient water level indicator using just a single ULN2003 IC! As soon as it detects water, the LEDs light up step-by-step. Connections and details are in the video, make sure to try it out! #electronics #DIY #uln2003 #waterlevel @𖣂Ö𝖒𝖊𝖗𖣂
