Parallel Programming and GPIO State Feedback in Nodemcu.

In this video, I've demonstrated a project to change the Intensity of the AC Appliance with Hand Gestures using Ultrasonic Sensor. Also I'm using a DHT sensor to upload the temperature and Humidity to Node-red in every 10 seconds and to run both the tasks parallelly we are using schedulers. The Problem statement - If we use DHT sensor with Ultrasonic sensor we need to introduce a delay of 10 sec in the loop part otherwise the DHT sensor will push the data to the MQTT broker continuously and if we use delay, then it is impossible to get the gesture reading from Ultrasonic sensor all the time. Here are a few Important links regarding the project. 1. Making a Dimmer Circuit with ZCD - /watch/A7Vxha8jIEIjx 2. Adding a Physical Button to control the GPIO - /watch/cPeoTPJbS3vbo 3.
