Below mentioned simple GSM arduino project where you can control any thing through GSM module . Here SIM900A used , need 3.7 , 2 Amps power supply must for SIM module , ground must common . Simple AT commands use to get output from the module , Pin 7 & 8 of Arduino used as TXContinue reading “GSM Based Home Automation System using Arduino”

Below is a simple  Arduino GSM Jammer (900 MHz) For 1800 MHz another VCO can be used. The square wave from Arduino pin 10 fed to VCO tuning volt input which will almost cover the Required input voltage from 0.5 to 5 volts to cover the frequency range from 870 MHz to 980 Mhz —————————————————-Continue reading “Arduino GSM Jammer”

This simple project can set the generator in automatic way to start the generator on low battery levelspecially for running network system #include   //Default Arduino LCD Librarey is included int Read_Voltage  = A0;int Read_CUTOFF  = A1;int led  = 8;int led1  = 9;const int rs = 12, en = 11, d4 = 5, d5 =Continue reading “Generator start Timer ( on Low Battery capacity )”

Russian PI metal detector circuit.Classical Russian PI detector where only few components were used working fineLM555 , TL062 , IRF 740 or 840 . ( IXQT0460P2 in my case)Contentious tone from speaker but change in tone if metal found KIT: 1500 PKR Testing video click below link https://www.youtube.com/watch?v=8ApYCEoK97Q

Very common Bluetooth Remote control Programming Arduino Nano  from Arduino UNO  1). Remove Atmega 328 from Arduino UNO 2).  Connect Arduino UNO  pin RX to Arduino Nano RX3).  Connect Arduino UNO  pin TX to Arduino Nano TX4). Select COM 6 ,as Arduino UNO on COM 6 Simple programming but need to be updated #include SoftwareSerial mySerial(10, 11);Continue reading “Arduino Bluetooth Remote Control (Home Appliances)”

Below is a simple car mobile charger made from a classical power regulator IC 317Here only 3 components were used ,Which are LM317 ,560R, 5K (variable) .Simply adjust voltages to 8.7 V DC (for fast Charging support mobiles).Actually in adaptive fast charger there are 2 outputs 5V & 9V .Any mobile supporting fastcharging send aContinue reading “CAR FAST MOBILE CHARGER”

Here is a simple FM radio with Ardiuno  board ,Which required popular Radio module called  RDA5807M. The RDA5807M series support frequency range is from 50MHz to 115MHz.Easily available in the market i simply find this module in MP3 players available in the market , this modules is without 32khz crystal, you need to placed thisContinue reading “ARDUINO FM RADIO”
