Discontinuity in breadboard's power rails
Make sure your power rails are properly connect. Supply power to the left hand side does NOT power up the right hand side. Break lines indicates discontinuity.
Capacitor polarity
Two types of capacitors are provide: polarised and non-polarised.
When connecting non-polarised capacitor, you do not need to worry about the direction.
For polarised capacitor, negative lead usually came in with a shorter leg, while the positive lead with a longer leg. On the packaging, look for negative symbol ( - )on a coloured band, it also indicates this leg is the negative lead. When connecting, the simple rule is: positive to positive, negative to negative (e.g., + to input, - to GND).
OpAmp Pinout
Always check for OpAmp's pinout and look for the right package.
Most of the OpAmp chips contains 2 OpAmps each, but there are chips come with 1 single OpAmp.
Check carefully before connect the OpAmps as well as power supplies. Position 1 usually marked with a dot, while the trench on the chip corresponding to the semi-circle trench on the plot.
