Congratulations! You finally have a garage to call your own and you’re ready to turn it into the workshop of your dreams. But before you go on a shopping spree in Home Depot’s tools section, you may want to consider upgrading from that single dim lightbulb to more substantial lighting — otherwise, you’ll never find the screws you drop on the ground. LeMaster Tech can help with his great video on installing DIY voice-controlled smart LED lighting.
LeMaster Tech’s primary goal was simply to increase the brightness in the garage. He took the route that gives the best bang for the buck: LED tubes. Those are similar in form factor to fluorescent light tubes, but they can put out more lumens with fewer watts and they tend to last a lot longer. They also don’t need expensive and bulky ballasts. LeMaster Tech installed several of those on the ceiling of his garage, then took things to the next level.
These LED light tubes work with standard household mains AC power, so they can be wired like regular light bulbs. But instead, LeMaster Tech made them smart by wiring them through a relay board controlled by an Arduino UNO Rev3 board. That lets the Arduino safely switch each light tube on and off. LeMaster Tech gave it the ability to do that in response to voice commands by adding a DFRobot Gravity voice recognition module. That handy module works entirely offline and uses a simple AI to recognize spoken words. It has 121 built-in words and supports 17 custom words, so LeMaster Tech was able to tailor it to his needs.
Now he can switch the lights with a simple voice command and even activate pre-programmed effects, like flashing the lights.
