Use Raspberry Pi To Control Light Switches

Raspberry pi will host a local webpage which contains the remote switch and also connect to wifi.

Use raspberry pi to control light switches.

How can one let the computer push the button. Running the program to use the reaction timer load and run the program 07 reactions py in mu. This device is connected wirelessly to a raspberry pi controller via local network. 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.

Basically i want to control the light socket switch to on off via a remote control. 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. Often you want to control modules with a higher voltage with the raspberry pi. So user may use a phone connected to wifi to open the local webpage and turn on off the light.

Using figure 2 as a reference connect the gpio pins on the raspberry pi to the breadboard using five female to male jumper wires. The relay switch works how a switch normally works however it operates using an electrical source the raspberry pi. The switch looks something like this. Raspberry pi will be used for the remote switch.

They can work in either spst spdt or dpdt type configuration. I though about using the raspberry pi to switch on and off other electrical devices which unnecessary consume power in stand by mode. What i plan to do is mount a device on the socket switch. We will do a practical demonstration with a raspberry pi to light up an led using the spst toggle switch.

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. 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. Connect breadboard to raspberry pi. The relay switch is utilized by means of a low voltage pulse.

For this purpose relays can be used on the raspberry pi. 220 ohm resistor. In short i d like to control an ac socket or multiple sockets. Toggle switch spst led.

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. Of course i had a backup of the software created using dd directly from the sd card but no spare raspberry pi. Cc by sa 3 0 by firstfreddy.
