Solar Tracking System Using Arduino and LDR | DIY | Automation | Robotics | Arduino | Technology |

Hello guys i have prepare this short DIY video on Solar Tracker which is very useful of solar panels / solar cooker and solar umbrella to adjust its self towards sun sunlight this system works with the help of 4 Light Dependent Resistor Each on four corners . So when ever the light gets blocked on corner the the servo rotates towards the light so the LDRs will be Parallel to source of Light You can follow this video and prepare this project for your schools Science projects and after a simple modification you can connect it to internet device and measure luminous intensity of light and monitor the battery charge and output voltage of your panel and you can use it as advance project.

DIY Smart Lock with Arduino and RFID

You walk up to an invisible lock that only you have the key for, and open it without even touching it. Sounds cool? Today we are going to build a simple RFID-based smart lock using an Arduino as the backbone and a few cheap components.

The technology behind this project is already used in many industries. Anyone who has worked in a modern office or used public transport will probably have used it every day. RFID (radio-frequency identification) identifies data stored on a chip in a card or dongle, and compares them to a list of tags that have already been scanned.

AI Talking Plant with Face recognition built with JavaScript and Arduino

The new talking plant has AI powered face and object recognition, voice assistant capabilities inhereted from Amazon Alexa and a lot of sensors you can ask questions about! He has light, tempereature and soil moisture sensors and a motion sensor to wake up when someone walks into the room. He can see if you are holding a glass or bottle of water in your hand and will ask you to water him! He also remembers the last time he saw you and will try and recall that memory. AI powered recognition is powered by AWS.

Arduino Network Tester

How many times you wanted to know if an Ethernet plug or port has internet connectivity and you had to bring your laptop or a cable from the next room to check? And how many times the only tools available were the simple Network Cable tester and your provider’s Modem or Router? For me that was a common issue and of course there was no easy, “plug and play” solution (at a reasonable price!!). Taking these into consideration I decided to give a solution by making a simple optimization to the most common Network tool. Arduino Network Tester, extends the functionality of the well-known Network Cable tester by adding DHCP, DNS and Internet connectivity tests using an Arduino Pro Mini and a W5500 Ethernet Shield with an overall cost of less than €15!
