Today we have start installing our components on the breadboard we had bought yesterday. Through this circuit we learn a lot of things. First of all we know how to read the value of capacitor. For example 102 mean 10X102 pico. We also learn the function of the 741 operational amplifier and LM386 Low Voltage Audio Power Amplifier. The component had been installed on the breadboard, however we just figure out that there is no power supply of -9v. Therefore, we can only wait on till this coming Monday to try our circuit to test whether it is success or not.
Below is the picture show the arrangement of the components on the breadboard that we had installed:
