Parking in tight spaces can be challenging, especially when there’s limited visibility. To help avoid collisions with obstacles, this project will show you how to build an Arduino Parking Sensor using an ultrasonic sensor and a buzzer. The ultrasonic sensor detects the distance to an obstacle, and the buzzer produces …

SOC audits are essential for ensuring the reliability and security of an organization’s systems and processes. The two main types, SOC 1 and SOC 2, have distinct purposes and focus on different aspects of operations. Understanding these differences is crucial for businesses aiming to maintain compliance and build stakeholder trust. …

I have shown how you can use ESP8266 to host a web server via HTTP and via WebSocket, use MQTT and ThingSpeak for sensor data, and even use Google Sheets. This time, I will be sharing with you how I send data between two ESP8266.
