I wrote about the Victorian history, physical sensor mechanisms, and networked logic of traffic lights! This is the fifth installment in the "How The Heck" series, following QR codes, GPS, Shazam, and solar panels. Hope you enjoy it! perthirtysix.com/how-the-heck-do-traffic-lights-work

Amazing write up from Shri as always. I love this micro-viz for getting across how these things worked really quickly/intuitively

Always love seeing your writing and datavis pop up! Would love to get a behind-the-scenes look at how you’re crafting these interactive models 👀
