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
Hey guys, we are thrilled to announce the speaker Mr. Brian Douglas for our upcoming event organised by HackClub TIST as part of Hacktoberfest 2020. He will guide you through GitHub and the importance of Open Source contributions.
Mr. Brian Douglas has been working as a Staff Developer Advocate at GitHub for the past three years and was fully on-board with us when we contacted him about the event.
We at Hackclub TIST strongly believe in the power of collaboration and how even the smallest guidance can have a huge impact in the long run.
So register now at http://hackclubtist.tech/hacktoberfest and lets git learning (pun intended).

@Anudeep Thanks a lot m8, I actually made a very silly mistake of including the https:// while entering FIREBASE_HOST, where I must have entered the Domain name alone and removed the https:// extension.
Thanks again for replying that quick. Cheers.
Hello @Palani, In the Firebase, there are two types of storage,Cloud Firestore (Very recent one & NoSQL database) Realtime Database (To which we upload the data using NodeMCU)
In the Arduino Code, you can see that there is a variable named FIREBASE_AUTH.
This variable should be assigned to the Database secret. This you can find in Project Settings -> Service accounts -> Database Secrets.
My mistake is, i have mistakenly assigned thay to Web API key. This is found at Project Settings -> General.
The error can also occur when u don't initialise a proper realtime database in Firebase. (This is not my case).
@Anudeep Hello Anudeep could you please help me out by elaborating the fix to get rid of that error?
Thanks in advance.
