08. Using a potentiometer to control the blink rate of an LED

The supplies and hardware setup is exactly that of the previous project. In this project, we will see how the potentiometer affects the blink rate of an LED.

Supplies

  • LED
  • Resistor - 220Ω
  • Potentiometer


  • Arduino Uno R3
  • Solderless Breadboard - Mini

Setting up your hardware



Connections

  • Cathode (LED) ---> Ground (GND)
  • Anode (LED) ---> D9
  • Middle pin of potentiometer ---> A0

Coding

Final Look

51. Buzz wire game using Arduino

Hello everyone! This is my first Arduino project in 2020 and it is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino. Hardware components used in this project Arduino Nano USB Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini and Full-size LEDs (x2) - Green and Red Resistors (x2) - 220 Ω  Active Buzzer module (KY-012) LCD display module with I2C interface - 16x2 Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x5) - 20 cm Jumpers (x5) - to reduce the usage of wires Copper wire  Tape (or any form of insulation)  Setup Your hardware setup must look somewhat similar to the ones in the images above. The beginning and end of the copper wire maze must be taped to prevent conductivity between the wire loop and maze. Connections LCD display module with I2C interface GND - Ground VCC - 5V SDA -...

85. Analog and Digital Clock on Adafruit TFT Display using Arduino

 Hey everyone, Sorry I have not posted in a while. Today, I will be presenting you my Analog and Digital Clock on Adafruit TFT Display using Arduino. You can find the schematic and code explanation within this post. Read on further to learn how I did this project. Hardware components used in this project Arduino Mega 2560 Adafruit 2.8" TFT Touch Shield for Arduino w/ Capacitive Touch - You could also use any other Arduino compatible TFT display DS1307 RTC Module Solderless Breadboard - Half+ (This is optional if you are connecting the RTC module to the development board directly) Jumper wires (x4) - Male/Male jumper wires if using solderless breadboard. Female/Male if connecting RTC module directly to Arduino Mega. Software apps Arduino IDE - latest version is recommended Setup Connections DS1307 RTC Module SCL - A5 SDA - A4 VCC - 5V GND - Ground Adafruit TFT Touch shield You can simply place the Adafruit TFT Touch shield onto your Arduino Mega 2560 development board. Make sure to...
