Electronics lesson: electronic parts, electronic components, electronic projects, circuit diagram and more
The following diagram is the schematic diagram of simple and cheap mini amplifier circuit.
The circuit built based SSM2211. I have never heard about this IC before, this IC may be quite difficult to find in the market, so before deciding to make this circuit, you better look for information about availability of this component in the nearest electronics store.
Sound generator circuit build based on 555 timer IC. This 555 circuit has a flip-flop circuit too, so there are will be 2 kind of outputs, that are a sound output and two blinking LED.
Parts list:
R1, R7 = 470Ω
R2 = 1kΩ
R3 = 68Ω
R4, R6 = 56kΩ
R5 = 47kΩ
Above diagram is the schematic diagram of stereo amplifier, build based integrated circuit STK4141II. This stereo amp will deliver about 25W power output on each channel. Take a note that a heatsink must be attached to the power IC STK4141II to prevent overheating.
