Home Automation System Using Smartphone and Bluetooth Part 2 With Manual Control
Hello friends welcome back to "Techno-E-solution", In previous video we see how we can control the home appliances with the help of Smartphone & Bluetooth but there is no any manual control for the system, so In this tutorial we are going to make a Smartphone control as well as manual controlled home automation system with Complete details.

LET'S MAKE PCB
Follow the following process for Making PCB Using Tonner Transfer Technic.
If you want to real PCB, I provide Gerber file below check it.
- Take a Single Sided Copper Clad PCB Board
- Cut the PCB as per PCB Layout
- Remove the dirt & rust from the PCB by using wire scrub or sand paper
- Place layout print on PCB & Heat the PCB with the help of Iron for 5-10 Min
- Take water in the container & deep the PCB into the water for 5 min
- Slowly remove the paper from the PCB
- Now take 2-3 spoon of ferrite chloride powder in container with water
- Deep PCB into the solution for 5-10 min for etching process
- After etching completed clean the excessive tonner from the PCB
- Drill The PCB with the help of PCB drill machine
- Now place app components on PCB & Solder It
- In this way the PCB board is completed.
