    How to adjust a Buck Regulator???

    Good day. I have this Circuit using A8447. My output voltage is 5V. My problem is I dont know where is(are) the divider resistor(s) to vary my output into 7.5V. Can somebody here help me how? Also, do i need to remove the connection of Vbias and Vout if im going to target an output voltage...

    Arduino Coding..

    long A = 0; int x = 0; long pulse; long counter = 0; void setup() { pinMode(A0, INPUT); Serial.begin(9600); delay(1000); for(x = 0; x<=60000; x++){ A = analogRead(A0); if(A >= 20){ pulse = pulse + A; counter = counter + 1; } } Serial.println(counter); Serial.println(pulse)...

    Arduino Coding..

    Im having a problem in what point to set before the variable will increment because the analog reading is a series of 0's and exponentially goes up to series of around 730 and drop down to series on 0's again without a definite time when and how long the pulse is. The time each pulse last is...

    Arduino Coding..

    Exactly Sir! It's from analog out of my cicuit and going to the arduino Analog pin.

    Arduino Coding..

    Yes Sir, The value that'll be displayed on the monitor should be the amount of pulses it have in a defined time, for example 60seconds..

    Arduino Coding..

    I have a problem in coding this graph in arduino. As i display the serial monitor, it logs analog values up to 730units. the value is indicated in the attached graph.. My objective is to count how many pulses(high) there have in a defined time. Can I ask for a help. Thanks in advance.. Very much...

    Cant figure it out..

    ** the battery that I used below is somewhat like from motorctyce battery so i choose not to place an overcharging circuit. ** I want to use the solar panel ONLY for charging the battery but it wont supply my arduino. Only the battery must supply power to the microcontroller. HOW can I make a...

    How does it works???

    Im so cunfused on how does it works??? -.- I have here a simple block diagram of my remote controlled V-camera. I dunno how the camera started to record video whenever I pressed the button in the Remote control??? By the time I had turn on the switch, the 5V goes in to the video camera(indicated...

    What Software to use???

    Ill be having a circuit to simultaneously trigger both camera and GPS device Sir so they are closely synchronized( though there will have a discrepancy in time but it is very minimal). Video cameras with built in GPS do exist Sir and that's why I became more enthusiast about this. To create my...

    Quadcopter with GPS?

    Hello Felas! I have a quadcopter toy and just had wanted to build it with a something that can capture/save its location with coordinates. But I'm not familiar with GPS devices. I want to now specifically what I'll be needing. Do I need to purchase a GPS receiver or a GPS module can stand...
