05. Controlling an LED using a Push-button (with debouncing)

As you already saw in the fourth project, push-button is a mechanical switch. Debouncing becomes useful when we want to make the push-button to perform like a toggle switch.
The supplies and hardware setup is exactly the ones mentioned in the fourth project.

Supplies:

  • LED
  • Push-button
  • Resistors - 220Ω and 10kΩ
  • Arduino Uno R3
  • Solderless Breadboard - Mini
  • Jumper Wires

Setting up your hardware




Connections:

  • Cathode (LED) ---> GND
  • Anode (LED) ---> D3
  • Push-button ---> D9

Coding

There will be a slight difference in this coding when compared to that of project 04.

Final look

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...

77. Controlling Micro servo Robotic Arm with MPU-6050 sensor module

 Hey everyone! I am back with an interesting project. Today, you will be learning about controlling a Simple 2 axis Robotic Arm, made from Micro servo motors, with an MPU-6050 sensor module. Please feel free to visit my previous blog post to learn about the MPU-6050 sensor module. Hardware components used in this project Arduino Mega 2560 - You could use any other Arduino microcontroller, but make sure you use an external power supply. USB Type A/B cable (for Arduino Mega 2560) MPU-6050 sensor module SG-90 Tower Pro Micro Servo motor (x2) Male-to-Male Jumper wires (x6) Male-to-Female Jumper wires (x5) Setup Schematic MPU-6050 sensor module VCC - 3.3V GND - Ground SDA - D20 (Arduino Mega 2560), A4 (Arduino Uno and Nano) SCL - D21 (Arduino Mega 2560), A5 (Arduino Uno and Nano) INT - D2 Micro servo motor (Roll) S (Yellow/ Orange) - D9 + (Red) - 5V - (Black/ Brown) - GND  Micro servo motor (Pitch) S (Yellow/ Orange) - D10 + (Red) - 5V - (Black/ Brown) - GND Coding As I alread...
