LM3915 10 LED Sound Audio Spectrum Analyzer Level Indicator Kit DIY Electoronics Soldering Practice Set

It comes without instructions.

Disappointed, 2 pieces are missing

When soldering, contact areas for soldering come off. I don't know what's wrong, maybe the heat is set too high. soldering iron is not adjustable. You need to order a soldering kit. with a good soldering iron with good temperature regulation. I repeat once again - the board is of poor quality. when overheated, the contact tracks come off.

The order took 16 days❤️. Everything is whole in the navel📦 The tracks are very thin, 3 pieces broke. that's why I had to solder 🥲 the LEDs are not the same as in the picture, and I saw that 2 sets of wires will be black and white and he only has 1 such 🫡 . Everything works
