Скачать или смотреть LM358 Op Amp LED Indicator (Red & Green) | Simple Voltage Test Circuit

Eksperimen lanjutan pakai IC LM358, kali ini dengan dua LED — hijau dan merah.
LED hijau berfungsi sebagai referensi tegangan ±2V, sedangkan LED merah jadi indikator output comparator.
Simple tapi efektif buat proyek seperti auto cut-off, voltage detector, atau indikator baterai DIY.

Continuation of LM358 test — now using Dual LEDs!
Green LED = voltage reference, Red LED = output indicator.
Simple • Visual • Reliable 🔋
