There are two folders in a Raspberry (video1 and video2). When the Rasp starts up, a looping playlist of the videos contained in video1 is played. I have an HC-SR04 sensor with nodeMCU connected to an ESP8266. When a person walks in front of the sensor (dist < 30 cm) the playlist is interrupted and the first video contained in video2 is started. When this video finishes, playlist execution resumes with the video that was running at the time of the interruption. When a second person passes by, the playlist is interrupted again and the second film contained in video2 is played, and so on. When the movies in video2 finish, the first movie is played in the next step. I want to use Mqtt. Translated with (free version)

We are a 2 person start-up business focusing on baby products and we need help with our first flagship product. We have a product vision that we believe can make a difference to the lives of new parents, and we need electronics support to make it happen. So far we have come up with a concept design and I have built up the demo rig using a NodeMCU ESP8266 dev kit, but I need to convert that into a packaged PCB that can be integrated into the product. There is a product that is already in production that does most of what we need already, so the job could be reverse engineering with some extensions (different screen and LEDs). So far the components that I think I need are microprocessor, Bluetooth, WiFi, memory, temperature and humidity, screen, LEDs, buttons, an power connection,...

The project is to set up multiple car detector ( Basically a metal detector ) in a parking area to detect if a car is present or not . Also the metal detector will be connected to a wifi network( via nodemcu or any other IoT board) which will be powered on board (battery). There will be multiple IoT metal detector which will be deployed in a parking lot and all will be connected to a wifi to get the data . The detector will send a notification to a mobile app or website (custom app or website) or any other pre made website or services . If a car is on the parking lot for more than a minute than a notification will be send to the app/website . The size of the IoT metal detector should as small as possible . We want the plan , code and circuit diagram .
