I set up and typed the code, so the LEDs light up and nothing happens. can someone explain to me why this happened? I'm a beginner and I don't have much experience in it. can you please give me more tips?
Matrix ke cathode ko negative supply dene ke liea npn transistor use karte hai. Agar aap bina transistors ke karna chahte hai to apko arduino me programming karni hogi ground ke liea.
nice video bro, u explain step by step with slowly
Circuit diagram please

Check your circuit connection
Bc 547 ka use karne ka reson kya hai
Kya uske bina nai ban sakta led matrix
