Introduction: Simple Wireless Doorbell DIY
Hello everyone,
Here I will show you how you can make a wireless doorbell at home easily at very cheap price.
I will provide you each & everything required for this project.
In this project I use JLC-PCB for my pcb...
They provide 10 PCBs for $2 only...I think this is great....
So lets make it...
Step 1: Watch the Video
Step 2: Order Your Pcb
To order your pcbs...
1. Open JLCPCB.COM
2.Upload your gerber file
3.Select your quantity/colour & other requirements
4.Now add your shipping address & Payment method
5. Pay for your order
You are Done
