This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. Advertisement ...

In this tutorial, we are going to design an Arduino Uno based Robotic Arm from some cardboards and servo motors.Entire process of construction has been explained in detail below. Here in this project ...

Some other modules come with an extra antenna pin. The working voltage of the transmitter module is 3V-12V and this module doesn't have any adjustable components. One of the major advantages of this ...

Arduino Weather Station This Arduino Weather Station project utilizes a DHT11 sensor to measure temperature and humidity, displaying the readings on a 16x2 LCD screen. The code is designed to be ...

PighiXXX is known for their very useful and pretty pinout diagrams, but they’ve now created a book called “ABC: Basic Connections” comprised of a collection of easy to read circuit diagrams that shows ...

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

Three separate outputs are taken from pins 3, 9 and 10 of Arduino board. Pin 3 is for square wave, pin 9 for sine wave and pin 10 for ramp wave output. Pins 9 and 10 outputs are actually pulse width ...

Fig. 1: Circuit diagram of millivolt meter. The Arduino is the brain of the circuit that calculates the voltage based on the ADC value using the program, which is displayed on LCD1. The voltage at ...
