  LED brightness control using Arduino and potentiometer. In this tutorial, we are controlling the LED brightness using the potentiometer. This is an easy tutorial for demonstrating how can we control the brightness of an LED or adjust the speed of a DC motor using Arduino Board, and potentiometer. in this tutorial we have used the three LEDs yellow, blue, green to control the brightness of the same.   Circuit Diagram: Components Required: §   Arduino UNO §   Yellow LED §   Blue LED §   Green LED §   Potentiometer 10K §   Connecting wires   Connection: The hardware part of this project is very simple and easy to place together. First of all, make the connections for LEDs with the Arduino. Connect the anode of the yellow LED to the digital pin12 of an Arduino. Connect the anode of the Blue LED to the digital pin 8 of an Arduino. Connect the anode of the Green LED to the digital pin 4 of an Arduino. Connect the cathode pin of all LEDs to the GND pin of an

  Interfacing Seven segment display with Arduino In this project, we will interface seven segment display with an Arduino For various application in day-to-day life, we need display to show the values and much more things, and there is no point to use expensive OLED and LCDs available in the market. Then what is the solution for this so we are having less expensive display and that is a simple seven-segment display. It is mainly use to display the numbers and some alphabets. Seven segment display has 7 LEDs which are arranged in the shape of 8. See the image below. Circuit Diagram: Components Required: §   Arduino UNO §   Seven Segment Display §   Resistors -02 §   Connecting wires   Connection: The hardware a part of this project looks quite messy but if we go step by step its simple and easy to place together. First of all, we make the connections for the 7-segment display with the Arduino. The connections for 7-segments with the Arduino given in the above circuit diagram and bel
