This is well known 555 astable mode circuite. I wanted to test R1, R2 and C1 values. t1 (High time of square wave)=0.693*(R1+R2)*C1, t2(Low time of square wave)=0.693*R2*C1, T(Period)=t1+t2 and F(frecance)=1/T
İf we need to design this R1, R2 and C1 values according to designg process we can use following formülasyon. F=946Hz Duty %52 and C1=2.2uf in this case acording to above formulas R1=27.73, R2=332.74
