Hello guys, how are you all doing?
During the past few months I've been going through the Textbooks AAC has published, experimenting with some minor circuits and even PIC microcontrollers. I've learned a lot during the process and decided to do something a bit more challenging - make a basic home security system that would be powered from the 240VAC grid.
This is my first time making something that relies on the local grid, so I decided to check with you guys before starting.
The voltage in my country varies from 220V to 240V, and has a frequency of 50Hz. I decided to use a 250V 1A fuse for overcurrent protection, and 4x 1N5408 diodes to make a rectifier circuit. The 240 DC voltage is divided using the 480 & 30 Ohm resistors respectively to bring it below the maximum input voltage required to operate a L7805 Voltage Regulator.
What do you think?
Thanks!
