I though about using the raspberry pi to switch on and off other electrical devices which unnecessary consume power in stand by mode.
Use raspberry pi to control light switches.
Unfortunately one day the raspberry pi running the nodered app passes by in smoke and it was not possible to switch these lights any more.
They can work in either spst spdt or dpdt type configuration.
The main concept of home automation using raspberry pi or any other platform like arduino is to control different electrical loads using raspberry pi.
The relay switch is utilized by means of a low voltage pulse.
How can one let the computer push the button.
Since the pi only tolerates a maximum of 5v the gpios even only 3 3v without relays there is the risk that the pi could burn out.
The relay switch works how a switch normally works however it operates using an electrical source the raspberry pi.
Our raspberry pi cannot turn the lamp on by itself so we use a relay switch to simple break the circuit when we want the lamp off and then connect the circuit when we want it in.
Basically i want to control the light socket switch to on off via a remote control.
Raspberry pi will be used for the remote switch.
We will do a practical demonstration with a raspberry pi to light up an led using the spst toggle switch.
In short i d like to control an ac socket or multiple sockets.
Of course i had a backup of the software created using dd directly from the sd card but no spare raspberry pi.
This is what we ll do today i ll start by introducing the product then the raspberry pi preparation and finally we ll see some code you can create to control your lights from basic tests to more complex scenarios.
Often you want to control modules with a higher voltage with the raspberry pi.

Raspberry pi will host a local webpage which contains the remote switch and also connect to wifi.
Connect breadboard to raspberry pi.
Toggle switch spst led.
In order to do this you need to understand how to control a relay using raspberry pi as relay is the main component in controlling electrical loads.
The switch looks something like this.
On raspberry pi it s possible to use the python programming language to connect to the api and manage the lights at home.
Using figure 2 as a reference connect the gpio pins on the raspberry pi to the breadboard using five female to male jumper wires.
What i plan to do is mount a device on the socket switch.
The most common type of switch you will see in most projects are toggle switches.
220 ohm resistor.
Running the program to use the reaction timer load and run the program 07 reactions py in mu.
