A few decades ago no one would have thought about automatic lights as a reality. But nowadays it is possible with the help of some budget-friendly electronic components. You just go into the room and see the magic happen, your LED bulb will glow automatically. The project we are going to discuss in this article does the same, we named it “Motion sensing lights”.

Now you might be wondering about the working of these lights, well the key component of these lights is “Passive Infrared Sensor”, abbreviated as PIR senor. Upon which Motion sensing lights work.

Story This Robotic Arm is made without Arduino. It works on a 2.4gh Transmitter which is commonly used in drones therefore I am using a FlySky FS-ia6 worth 5500 inr. I also used a 3mm Acrylic Sheet to make its arms. Servo Motors used are Tower Pro Mini Servos and they works on 5v and also the reciever works on 5V thats why i used a 5V 2A Power supply which can be provided using a Mobile Charger. This Project is good for School and Colleges Projects, Science Exhibitions and for hobby too. You will need – 1. 4x Servo Motors 2. Acrylic Sheet 3. Drone Transmitter Tools Needed – 1. Screw Driver 2. Acrylic Cutter 3. Double Sided Tape 4. Cutter Servo Motor A servo motor is a closed-loop system that uses position feedback to control its motion and final position. In industrial type servo motors the position feedback…

Story Our skin is amazing! It provides a medium for us to experience the sense of touch. It keeps infections out and keeps innards in but I bet you didn’t know that our skin changes conductivity depending on many different things one being our mood! It is called Electrodermal activity (EDA) and there’s a really interesting Wikipedia page you can read here. The basics are that our skin changes its conductivity depending on how we feel. So tody we are going to make a Lie Detector using Arduino. This lie Detector will detect if the person on whom we are testing this is telling a lie or not. We start by connect our Arduino to the subject. Then connect the Arduino to a computer with the graphing software (I’ll go over this in detail later). Lets start by asking the subject some easy questions. We know they will answer truthfully…
