Mosquito repeller

I nowadays mosquito is the huge problem and mosquito is also spreading many diseases and this DIY will really help you 

Here is a list of the components and tools required

  • Arduino Uno
  • PCB
  • Piezoelectric Disk
  • Header Pins
  • Wires
  • Soldering Iron
  • Soldering Lead
do as shown in video


 
upload the code from here

/*
 * this is an arduino project
 * for those who is getting sucked by mosquito 
 */
int speaker = "9" ;//first let set the pin for pizo disk
int frequency = "31000";
/*now lets keep the frequency 31000hz 
 * which irritate the mosquito
 */
void setup() {
  pinMode(9,OUTPUT);//set pin 9 as output
}

void loop() {
  tone(speaker,frequency,1000);//use tone command to set frequency
  /*
   * if you dont know about " tone "
   * select tone and press
   * Crtl + Shift + F
   */
   }

diy relay module

I If you want a relay module and you are thinking that you will buy it online here is a link Amazon.com : relay module
but as you see it is expensive i will tell you a very cheap DIY

material needed:-

vero board/prototyping boardrelay 12vdiode 40001 or 40007bc558 transistor9volt batterymale header pin or simple wire for connectingstep1:-
place all the thing on the veroboard as shown in picture or in schematic or in video
breadboard view
schematic picture


step2:-
connect signal to desired pin of arduino 
and ground to ground pin of arduino
and don't forget to connect 9volt battery

 finished


if it is not working check the diode position and transistor position and also see ground connections

pov display

pov display here is an exciting project for you all pov display this project will
float words in air and easy to made


material needed:-
Arduino nano (but can use any arduino) 5 leds 5 220 ohms resistor jumper wire battery vero/prototyping board switch (if needed)


instructions:-
first connect leds to vero/prototyping board
connect the led to vero/prototyping board be careful that the led should be connected to
digital pins 8,9,10,11,12 of arduino _________________________________________________________________________________________
after fitting leds to vero/prototyping board cut the excess board
cut it by using a sharp knife or scissor. ________________________________________________________________________________________ upload the code on the arduino // how long each led stays on forintdelayTime=4;//how long between each intcharBreak=3;//how long to wait after the message is finished before it repeatsintresetTime=20;intLED1=8;intLED2=9;intLED3=10;intLED4=11;intLED5=12;…
