Controlling a HVAC Relay With a NodeJS Web Server and a Raspberry Pi

In this video I control a HVAC relay using a Raspberry Pi and a NodeJS web server.

How to install an inverter in a pickup

In this video I install a 4000 watt dc to ac inverter in a pickup. I tried my best to repair the audio in this video, I will do a second video and narrate it because the audio did not come out good using the built in microphone on the camera.

Controlling a Type B Plug With a HVAC Relay and a Raspberry Pi

In this video I go over how to control a type b plug using and Raspberry Pi and a HVAC relay. I use the GPIO pins and Python 3 to turn on and off the relay controlling the type b plug. Follow Up video: https://rumble.com/v4aya4r-controlling-a-hvac-relay-with-a-nodejs-web-server-and-a-raspberry-pi.html Script: #!/usr/bin/python3 import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(3,GPIO.OUT) GPIO.output(3,GPIO.HIGH) #!/usr/bin/python3 import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(3,GPIO.OUT) GPIO.output(3,GPIO.LOW)
