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 […]

PrzemekM1@ instructables.com build a simple ESP01 development board. I hate to connect ESP01 modules on breadboard so I’ve made simple devboard with programmer, some LEDs and switches on board. Now I can easy test some IoT projects 🙂 Simple ESP-01 testboard – [Link]
LTC5596 – 100MHz to 40GHz Linear-in-dB RMS Power Detector
https://www.electronics-lab.com/ltc5596-100mhz-40ghz-linear-db-rms-power-detector/
The LTC5596 is a high frequency, wideband and high dynamic range RMS power detector that provides accurate, true power measurement of RF and microwave signals independent of modulation and waveforms. The LTC5596 responds in an easy to use log-linear 29mV/dB scale to signal levels from –37dBm to –2dBm, at accuracy better than ±1dB error over […]
Controlling A Robotic Arm By Gestures Using Kinect Sensor & Arduino
https://www.electronics-lab.com/controlling-robotic-arm-gestures-using-kinect-sensor-arduino/
B.Avinash and J.Karthikeyan had developed a robotic arm that mimic their moves using a Kinect sensor with MATLAB Simulink and an Arduino. The arm was built based on servo motors that replicate the right arm shoulder, elbow and hand movements. The Kinect sensor is a horizontal bar of motion sensing input devices which enable users […]

Environmental data display on an RGB matrix panel
https://www.electronics-lab.com/environmental-data-display-rgb-matrix-panel/
In this tutorial, I have described how to use a 16×32 RGB matrix panel with Arduino Uno for colorful display of environmental data captured locally using Bosch BME280 sensor. BME280 is a fully integrated environmental unit from Bosch that combines sensors for pressure, humidity, and temperature in a tiny 8-pin metal-lid LGA package. The RGB LED matrix panel consists […]
12$ 30MHz signal generator using Arduino
https://www.electronics-lab.com/arduino-based-signal-generator/
A signal generator is an electronic device that generates electronic signals and waveforms. These electronic signals are either repeating or non-repeating as per the requirements and field of applications. It is generally used in designing, testing, troubleshooting and repairing electronic devices. A signal generator can generate various kinds of waveforms. Most common are the sine […]
