The weekly report summarizes the progress of an engineering student group called 361 degrees. They have been working on a circuit project involving an MP3 module, memory, and amplifier. The MP3 module is functioning effectively but connecting the full circuit to test it has posed challenges. Next week, the group aims to integrate a microcontroller to trigger the MP3 module with a switch. Figures 1 and 2 show the memory socket and memory component of the circuit design.

Weekly Progress
Introduction : The concept of group.The machine is used, then relax,to feel comfortable.
Overall :In doing this work when the audio signal from the input module output signal is a sine
wave, the signal because to the interference signals or how difficult it is to have the best sound
quality in the module. The circuit of the light in the course of the experiments and connection were
carried out successfully. Circuit Power supply have been successfully modified after a fire in the
past week. An error occurred in. week of not having to calculate all the currents of the circuit
design to the current value of the too many. And the signal output from the memory cannot be
removed if the extension of the circuit to be Amplifier. Cs, no legs because memory can be found
inside the socket memory.

Engineering Analysis
Strong Point
The function of Module MP3 of the most effective.
Week Point
Connect The circuit together,In order to test the circuit. Can it actually works or not.
Next Week Job
Get away with making the switch to trigger the module MP3 with the severing of the
Microcontroller.
