IOT : THE RECEPTION ROBOT

I have made this simple IOT Reception Robot project. This project involves a robot to guide customers and a touch screen display for customers to interface.

Robot can talk to customers and remember the person next time by their name. It shares ongoing offers available at the shop. It also suggests what product to choose based on customer's requirement.

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ A load cell is a transducer that converts force (weight) into an electrical signal. The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales. Today we’ll connect a load cell to Raspberry Pi 3 using the HX711 module. 🧪 🔧 Components Required Component Quantity Raspberry Pi 3 1 Load Cell 1 HX711 Module 1 Jumper Wires 6 Breadboard (optional) 1 🔌 Pin Connections HX711 Pin Raspberry Pi Pin Pin Number VCC 5V Pin 2 GND Ground Pin 6 DT GPIO 5 Pin 29 SCK GPIO 6 Pin 31 Figure: Load Cell connected to Raspberry Pi 3 via HX711 💻 Python Code from hx711 import HX711 import RPi.GPIO as GPIO import time hx = HX711(dout_pin=5, pd_sck_pin=6) hx.set_reading_format("MSB", "MSB") hx.set_reference_unit(1) hx.reset()...

Interfacing Sound Sensor with Raspberry Pi 3

🔹 Overview The KY-037 is a high-sensitivity sound detection sensor that can detect noise levels in the environment. It provides both analog and digital outputs. In this tutorial, we’ll interface the digital output of KY-037 with Raspberry Pi 3 Model B+ (without using an ADC like MCP3008) and detect sound events.
