To program NodeMCU in Arduino IDE, we have to install esp8266 board (ESP8266 core for Arduino) to Arduino IDE. Add Additional Board Manager URL for ESP8266 board:> File > Preference Add “http://arduino.esp8266.com/stable/package_esp8266com_index.json” in Additional Board Manager URLs. Add ESP8266 board to Arduino IDE:– Open Boards Manager in Arduino IDE– Search “esp8266” or “NodeMCU”, you will find “esp8266 by ESP8266 Community”. Install it. That’s it

DIY Cheap & Portable Power Supply Version 1.0 There are a lots of power supplies in market but those are too expensive for a Arduino Beginner or a Hobbyist. So I decided to make a Good Looking and Cheap power supply out of cheap modules. the power Supply must be handy as well as Powerful. So I started with making a voltmeter using 7107 IC (4- 7 Segment display Compatible). I created a circuit Diagram using EasEDA.com and created a Schematics and Then created a PCB design for the same and ordered my PCBs from jlcpcb.com because they provide best quality PCBs in the market. All the Schematics and PCB Design can be downloaded from www.robocircuits.com link to files – http://www.robocircuits.com/digital-voltmeter-without-arduino/ Then for making the Power Supply I printed a 3D Enclosure for the PS and get it printed by a local 3D printer. Then I grab some components 1. Voltmeter – http://www.robocircuits.com/digital-voltmeter-without-arduino/ 2. Buck Conveter – https://amzn.to/2RfWbcG…

How to drive the Arduino color OLED The display is very small. It has almost the same size as the monochrome OLED display. But the resolution of it is not the same. It has a resolution of 96×64 pixels. So, it has a lower resolution at the same size. It can display 65 thousand colors! The display I bought, uses the SPI interface so we have to connect 7 pins in order to make it work. The monochrome ones that I have bought, use the I2C interface which requires only 4 pins. So, we need more wires in order to connect it with Arduino. Let’s how to achieve that. I am going to connect the color OLED display to an Arduino Uno. GND pin goes to Arduino GND. Vcc pin goes to either 3.3V or 5V output of the Arduino Uno. I connect it to the 3.3V output of the Arduino Uno.…

Dot Matrix 8×8 Make a cheap and good looking LED matrix Things used in this project Hardware components Arduino Nano R3 × 1 LED (generic) × 1 OSH Park Custom fabricated PCB × 1 Software apps and online services Arduino IDE Hand tools and fabrication machines Soldering iron (generic) Story Theory of LED dot matrix display In a dot matrix display, multiple LEDs are wired together in rows and columns. This is done to minimize the number of pins required to drive them. For example, a 8×8 matrix of LEDs (shown below) would need 64 I/O pins, one for each LED pixel. By wiring all the anodes together in rows (R1 through R8), and cathodes in columns (C1 through C8), the required number of I/O pins is reduced to 16. Each LED is addressed by its row and column number. In the figure below, if R4 is pulled high and…

By PrashantS161Follow Its not only a Quadcopter ,,,, Its a open source Machine!!!! Many of you face a problem when it comes to Flight Controller which is the brain of the Multirotor. There are plenty of ready-made pre-flashed Flight controllers in the market for cheap, But have you thought of building your own Flight controller with your Arduino? So this is the right place to understand and build your own Flight controller for your Quadcopter or Multirotor with your Arduino. Now the questions come, Where and how do I get the code for the quadcopter? So the answer is Multiwii. MultiWii is a Very popular flight controller software for DIY Multi-rotors with a large community. It has Support various Multi-copters with advanced features such as Bluetooth Control by your Smartphone, OLED Display, Barometer, Magnetometer, GPS position hold and return to home, LED strips and many more. So let’s build our Flight…

What is NodeMCU? NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. … It is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson, and spiffs. How to program it using Arduino IDE? Firstly open the Arduino IDE Go to files and click on the preference in the Arduino IDE copy the below code in the Additional boards Manager http://arduino.esp8266.com/stable/package_esp8266com_index.json click OK to close the preference Tab. After completing the above steps , go to Tools and board, and then select board Manager Navigate to esp8266 by esp8266 community and install the software for Arduino. Once all the above process been completed we are read to program our esp8266 with Arduino IDE. For this example I have…

Line Follower Robot Arduino Line Follower Robot follows a black line. arduino project infrared ir sensor line follower COMPONENTS AND SUPPLIES Arduino UNO & Genuino UNO × 1 SparkFun Dual H-Bridge motor drivers L298 × 1 Proximity Sensor × 1 APPS AND ONLINE SERVICES Arduino IDE ABOUT THIS PROJECT Line Follower Robot Best & Fast PCB Supplier (2$ for 10 PCBs) https://jlcpcb.com YouTube A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. Concepts of Line Follower Concept of working of line follower is related to light. We use here the behavior of light at black and white surface. When light fall on a white surface it is almost full reflected and in case of black…
