Build a smart waste detection system using ESP32-CAM and AI image processing. Classify biodegradable & non-biodegradable waste in seconds. Free API, full code included.

Burglar alarm system is an important part of home security systems. This burglar alarm project is based on PIR sensor, UM3561 and Speaker. PIR sensor used to detect body motion and UM3561 & speaker to produce Police siren after any movement detection.

In this project we are going to design a RFID based toll plaza system for security purposes. So this system open gates and allow people only with the authorized RFID tags. The authorized tags holder ID’s are programmed in to the ATMEGA Microcontroller and only those holders are allowed to leave or enter the premises.

SIM800L is a very compact GSM/GPRS module that can be integrated into a lot of IoT projects due to its compact size and flexibility.

Complete E88 drone teardown revealing internal hardware, flight controller, motor assembly, battery system, and WiFi camera module. Deep dive into budget quadcopter electronics.

This hands-on tutorial explains how to ditch unreliable SD cards and boot your Raspberry Pi models 3B, 3B+, 4, and 5 directly from USB or NVMe. It covers setting up USB-boot for each model—from enabling OTP on Pi 3B to updating EEPROM on Pi 4 and using native USB/PCIe boot on Pi 5, boosting speed, reliability, and convenience.

Keypads are widely used input devices being used in various electronics and embedded projects. They are used to take inputs in the form of numbers and albhabets, and feed the same into system for further processing. In this tutorial we are going to interface a 4x4 matrix keypad with 8051 microcontroller.

In this project, we will build a low-cost connected solution with a pre-designed Soil monitor using different components
