Customer:
I want to build a single housing with an LED light, a light sensor, and its own power supply. How can I use the Light sensor with LM393 (Soldered Electronics) with an LED strip and a button battery (5V)? What wiring diagram should I use? Also, can a 1m LED strip be shortened, and how? For example, can it be cut into 16 cm segments?

Želim na jadnom kućištu ugraditi led svjetlo sa senzorom svjetlosti i
vlastitim napajanjem.
Dali i na koji način (shema spajanja), mogu koristiti vaš SENZOR SVJETLOSTI
S LM393 (E-RADIONICA MADE), sa Led trakom i gumb baterijom 5V?
Dali se LED traka od 1m može skraćivati i kako na manje trake, recimo 16 cm
?

Soldered Support:
Regarding the button battery: a 5V button cell is not ideal for powering an LED strip because its capacity is very small and it will drain quickly. For this application, rechargeable lithium batteries are recommended instead. Concerning the wiring diagram for the light sensor, I can draw it up once we clarify the power supply details. Standard LED strips can be shortened: every 10cm for strips with 30 LEDs per meter, or every 5cm for strips with 60 LEDs per meter.

hvala na upitu!
Gumb baterija - mislite na ovo? https://e-radionica.com/hr/baterija-cr2032.html
Ako da, nažalost nije baš najbolja ideja koristiti takvu bateriju za napajanje LED trake jer je njen kapacitet jako mali te će se jako brzo prazniti.
Za nešto takvo, preporučamo litijske punjive baterije: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
Što se inače tiče sheme spajanja za senzor svjetlosti, mogu Vam nacrtati čim pojasnimo ovaj detalj s napajanjem.
Klasičnu LED traku možete skraćivati svakih 10cm(za onu koja ima 30 LEDica po metru) ili svakih 5cm(za onu koja ima 60LEDica po metru).
