In this project, we will learn how to get started with the ESP8266, an inbuilt 4Duino Wi-Fi module and connect to a local access point. The 4Duino display is used to print the status of the connection for debugging purposes. The ESP8266 Wi-Fi Module is embedded in the 4Duino....

Sverre Holm blogged about his Arduino clock project: But I needed another Arduino project as I had made a K3NG morse keyer. I love this keyer because it is unique in supporting a display where you can see what you send. But I wasn't using the morse keyer all the time, so I wanted...

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...

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...

fasoft @ elektormagazine.com has a new project proposal about a SD Card Sound Player. Searching for a powerful gong or acoustic notifier? The "Card Sound" consists of audio amplifier TDA7266 having 2x 7 W output, the AD converter CS4344, one STM32F401 and a slot for micro sd card....

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 -...

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...

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...
