Day 1: Introduction To Printed Circuits Boards
salmanfaris last edited by salmanfaris
One of the key concepts in electronics is the printed circuit board or PCB. It's so fundamental that people often forget to explain what a PCB is. This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world.
Here we are using Sparkfun PCB Basic tutorials, and after that, we have some ToDO that you need to complete.
Resource Link: https://learn.sparkfun.com/tutorials/pcb-basics/all
- Find the Annular ring, Drill hit, Finger, Mouse bites, Pad, Silkscreen, Slot on the PCB you used (ex: Arduino Uno, Relay) and Document it (Docs, Github, MakerGram..etc)
- List out PCB designing Softwares
- Download and Install Autodesk Eagle

can you please explain it again on why those gaps were made at the bottom of relay boards??

Hi @jerin_peter ,
The answer to your question is “isolation”. When designing electronics products involving more than one type of signal or more than one operating voltage, isolation is used to prevent one signal from messing up the other. It also plays a vital role in safety by preventing fault conditions in industrial-grade products. This isolation is generally referred as Galvanic isolation.
In the relay, we are using Power isolation and it's are required to isolate low power-sensitive devices from high power noisy lines or vice versa. Also, power level isolation provides proper safety from hazardous line voltages by isolating the high voltage lines from the operator and other parts of the system.

@salmanfaris Ohhh Thankyou sir, Well explained
@arunksoman thankyou so much...your reply really busted the stress out of me...can you help with any documentations which i could possibly go through
@sreu13 It is possible and a far far better method.
@arunksoman hi,..sending image from rpi4 to cloud using this cloud for running prediction the above two processes should be automated and image should be sent to cloud when pi boots up(VM engine can be activated whenever nessesary)
actually at this point of time, I'm not willing to risk RPI4,....i thought of connecting the rpi4 to google cloud (already have an account with $300 credit) and proceeding with the code.
but i do not know if the below process can be executed
is this possible?
@sreu13 I edited comment please read that again. Most probably it will not effect your file system. In some scenarios it can create worse effect.
@arunksoman i'll try this method, but while executing swap command, will the rasbian os and the files it contains be effected??
