            Homemade dual axis solar tracker Hello and welcome to the RC Invention projects. In this article, you will learn to make a dual axis solar tracker using Arduino, servo motor and LDR. Ingoing to use some  this poject, we are use some light sensitive sensors like LDR to track the sunlight and direct the solar panel towards the sun that increase its efficiency  Components required for this projects. 1. Arduino Uno or Nano. 2. servo motor (2nos). 3. LDR (Light Depending Resistor). 4. Resistor ( 1k to 10k ohm ) any one. 5. Solar panel . 6. PVC sheet . Circuit Diagram Arduino Code - 01   #include <Servo.h> // 180 horizontal MAX Servo horizontal; // horizontal servo int servoh = 180; // 90; // stand horizontal servo int servohLimitHigh = 180; int servohLimitLow = 65; // 65 degrees MAX Servo vertical; // vertical servo int servov = 45; // 90; // stand vertical servo int servovLimitHigh = 120; int servovLimitLow = 15; // LDR pin connections // name = analogpin; int ldrlt = 0;

How to Make Simple Arduino Humanoid Jumping , Dancing & Walking Robot

  arduino Dancing Autobot hello guys this is our  project..and new thats called autobot with dancing like michael jackson.... its amazing... we have made this cutting cardboard..but you can make this with using 3d printer.. now lets goooooooo..... Step 1:-components 1:-arduino uno/nano 2:-servo motor 3:-9v battery or power bank 4:-jumper wires 5:-mini breadboard Step 2:-servo Motor servo motor have 3pins you can identified by red ,black and yellow color 1st of all red color wire is connect to +5v black color wire is connect to gnd and yellow color wire is connect to microcontroller means to arduino. 4servo motor are used in this project.. so servo motor fix is important in this project.. see this pic..and follow how to connect this 4 servo motors... Step 4:-circuit Diagram fix your motors.. then connect 4servo motors to arduino.. all red wire of servo motor is connect to +5v black wire connect to gnd and yellow wire is connect to arduino pin.. see this pic.. 2servo motor is connect to

How to make talking Voltmeter at home

 Homemade talking voltmeter using Arduino   It's easy to make a simple digital voltmeter using an Arduino, Audio amplifier and Speaker It's relatively simple to use an Arduino to measure voltages. The Arduino has several analog input pins that connect to an analog-to-digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input.   Requirement 1. Arduino uno/nano. 2. Audio amplifier. 3. Speaker. 4. 100K ohm resistor. 5. battery .
