LED sensor

 

LED SENSORS

Required hardware :

1. Audrino

2. 10k ohm resistor

3. LED

4. 220 ohm Resistor

5. Breadboard

Circuit



. connect 3 wires to audrino

. red wire goes from 5V to breadboard, black wire goes from ground to breadboard, the white wire goes form analog input to breadboard.

. plug the LED longer part (the anode, positive part) to pin 13 through 220 ohm reisitor and the smaller part(the cathode, negative part ) to the ground(GND) in audrino.

Code



 

 


 

 You can adjust the speed of LED blinking.

Quantum Learning Companion

                                              Quantum Learning Companion In the not so distant future, quantum computing became an important part of curriculum and each student received Quantum Learning Companion, a type of device that uses quantum computing to enhance learning and personal development. Max and Emma two high school friend who were having difficulty in adapting the new technology . Max was an intellectual student always being curious of learning new gadgets. Max who had been using Quantum Learning Companion was enjoying its use in his learning while Emma was more concerned and tensed of the Quantum Learning Companion. She was scared of using it as she thought it might hamper her way of learning. On a sunny day, Max and Emma were sitting on the park, Emma worriedly sighing said she still is afraid of using the this new device as she thought it might...

Passive Infrared sensors

Image
  PIR is a device  which can detect sensor and infrared radiation that are emitted by any living beings(humans and animals), also due to this PIR are mostly used in house as a security. Hardware required : Arduino Uno Jumper Wires LED HC-SR501 Passive Infrared Sensor This PIR sensor consist of 3 pins (VCC, Ground pin , and Output pin in the middel) Here we will connect VCC of PIR to Arduino 5 volts. Likewise connect ground to ground pin and connect output pin of PIR to digital pin no.3 of Arduino. Lastly place LED positive leg  to  pin 13 and negative leg to  GND of Arduino. Code /the time we give the sensor to calibrate (10-60 secs according to the datasheet) int calibrationTime = 30; //the time when the sensor outputs a low impulse long unsigned int lowIn; //the amount of milliseconds the sensor has to be low //before we assume all motion has stopped long unsigned int pause = 5000; boolean lockLow = true; boolean takeLowTime; int pirP...
