Automation solution to tollbooth issues [human error, ticket vending machine failure, depressing job]. Creates fair pricefeed aggreation using Adapter.js with Chainlink API request with MTA website fee data being webscraped using Puppeteer.
What it does
Tollbooth smart contract with ultrasonic sensors and servo motors. Chainlink node scrapes,filters,scales and aggregates MTA toll fee data with Adapter.js. Chainlink pricefeeds remove need for ERC20 payments. Chainlink Keepers used to close gate [servo] 15 seconds after opened. Ultrasonic sensor sends closeServoGate() Tx with web3.py when distance under 30cm AND gate open.
