21. 4 x 4 x 4 LED cube

Hello everyone!

Today, I will show you how to make an LED cube (4x4x4). I have used blue LEDs but you are allowed to use any other colour.  This project took nearly two days for completion - one day to complete the structure and the next one to prepare the sketch. This project was specially designed for my Arduino Nano; unfortunately, the Arduino Nano had some issues while uploading the code. After several attempts, I realised that the problem was with the Arduino board and not my sketch. At first I used the Arduino Uno, but later I solved the issue with the Arduino Nano and used it.


 Supplies

  • LEDs (x64) - any colour
  • Metal wires - 4" long and 20 gauge thick
  • Resistors (x4) - 220Ω
  • Arduino Nano
  • Prototype PCB
  • Wires - Thin
  • Solder
  • Cardboard sheet/ Wooden plank/ 3D printed template

You may need some tools as well, which are:

  • Soldering iron
  • Needle-Nose pliers (for cutting)
  • Round-Nose pliers (for bending the metal wires)
  • Tweezers
  • Ruler - 15 cm


Setup



Using your ruler, draw a grid onto a cardboard sheet/ wooden plank with 9 squares, each with a dimension of 1"x1". Carefully poke/drill a hole onto the points where the lines meet, and the diameter of the hole must be equal to the diameter of the LED.

Place the metal wires above the LEDs and solder the wires with the anodes of the LEDs. Then, place two other wires, one at the top and another at the bottom, and solder it with the four wires. Repeat this procedure for other three layers.

Carefully place 16 metal wires (4" long) in an arrangement like the grid you've drawn and solder each layer with the wires.

Your cube must look similar to the one in the images above.

Connections

  • Layer 01 - A0
  • Layer 02 - A1
  • Layer 03 - A2
  • Layer 04 - A3

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...

57. Using Blynk with Arduino Uno and ESP8266 WiFi module

Hello Everyone! Today I am going to explain you how to connect your Arduino Uno with Blynk using the ESP8266 WiFi module. I have already demonstrated you about connecting your Arduino Uno with Blynk app using the Ethernet Shield W5100 and this will be the second version of that project .  Hardware components used in this project Arduino Uno ESP-01 ESP8266 WiFi module USB to TTL converter Solderless Breadboard - Half+ Breadboard power supply module - 3.3V/ 5V RGB LEDs (x3) - Common Anode Resistors (x3) - 220 Ω Relay module - 5V single channel Male-to-Male Jumper wires Female-to-Male Jumper wires Setup Your setup must look somewhat similar to that shown in the images above. Connections ESP8266 ESP-01 wifi module GND - Ground GPIO0- Not connected GPIO2 - Not connected RXD - D2 TXD - D3 CH_PD - VCC - 3.3V RESET - Not connected VCC - 3.3V  *Note: Do not connect your ESP8266 ESP-01 wifi module with 5V.

73. Limit the crowd to prevent the spread of COVID-19

Hey everyone! Today I am going to explain you about another interesting COVID-19 Arduino project. This is an automatic, effective and cheap method to limit the crowd in public places - such as shopping malls, supermarkets, offices, etc. - and public transport vehicles, such as buses and trains. The World Health Organization, WHO, has advised people to stay away from crowded places to protect themselves from the spread of Coronavirus disease. Even though people practice social distancing, it may not be effective when they are present in crowded places. I came up with this idea after I read the WHO guidelines about preventing the spread of COVID-19. Aim/ Objective This project is an automatic, cheap and effective way of limiting the crowd in public places and vehicles. Using a human to limit the number of people in a particular place would not be as effective as using an automatic system, due to lack of staff members in some areas. This prototype can be used in real-life situations by ...
