Simple Electronic Bell Generator using LM741
Today I begs for to advise Simple Electronic Bell Generator , with Linear IC Op-Amp the number is highly popular be number LM741. By when press S1 as a result , will have sound signal bell come out and lead this signal goes to amplify talk at one time with power Amplifier Circuit The general. For Circuit the this friends must use Dual Power supply Source 9 Volt. Detail sizes are other friends has seen in the circuit , which not difficult yes.
