Note: The information presented here is for educational purposes. This tutorial is designed to help users understand the security implications of using unprotected wireless communications by exploring its use in a popular drone model: the Parrot AR.Drone 2.0. It’s illegal to access computer systems that you don’t own or to damage other people’s property, the […]
Build Your Own I2C Sensor
https://www.electronics-lab.com/build-i2c-sensor/
Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Paweł Spychalski faced this problem while building his own weather station that is based on Raspberry Pi. It collects various […]
