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…
