In this mini project, we will charge any mobile battery using the output voltage from the circuit. Be it a simple project involving a single 8-bit micro-controller and some peripherals or a complex one involving system on chips (SoCs), 555 timer working is involved. Electronics Projects For Engineering Students 1 www. e the voltage dropped across the positive terminal of ic 741). I believe this Book will be helpful for. Mount the following: IC-I, 741 Op Amp. NOTE: IC sockets (like the ICs), have a small notch or dot to identify one end. It has to be turned off. I believe this Book will be helpful for. The mini projects using IC 741 listed here can be used as diploma level as well as high school level projects. 555 Generate PWM and L293D works as output driver. The circuit incorporates the versatile FIGARO TGS 813 gas sensor as the main sensing device. Simple electronic circuits to make mini electronic projects.
