This plotter, based on Arduino, allows you to draw on a vertical surface, such as a blackboard, using a normal marker. As you can see from the video, the central block, where the marker is located, is connected to two cables which, according to their length, make it move along the surface. The project is…
In this tutorial we will learn how to register fingerprints and then read them with the biometric sensor and activate a lock. The sensor works with the serial protocol, so it can be used with any microcontroller (Arduino UNO in this case) or development card. The device also has the ability to store up to…
The project consists of an automatic transistor tester, which allows you to identify the pinout and characteristics of various discrete semiconductors (NPN, PNP, MOSFET transistors, etc.). It is also capable of measuring resistors, capacitors, inductances and diodes. The original project was written in a mix of C and AVR Assembly Code; this instead uses an…
Today I am going to show you, how I build a “Racing Game Simulator” with the help of Arduino UNO. The working is very simple Arduino is use as a HID device that can communicate between computer and external componentdevices More info
Let’s see how to build a small piano using Arduino, a buzzer and aluminum foil. The principle used is the capacitive sensor, capable of detecting the electrical capacity of the human body. The sensor setup requires a medium to high value resistor, a wire and a piece of aluminum foil at the end. More info
https://youtu.be/IXAx29LAVCs In daily life, we inevitably touch various public facilities, such as the switch of the company’s water dispenser. Since drinking water is everyone’s daily and you need to touch the switch of the dispenser many times a day. In order to avoid cross infection caused by bacterial virus transmission as much as possible, I…
The main goal of this project is to protect our beautiful home from LPG gas leaking and fire accidents using an Arduino UNO board. More info
Thinking about what to do with a broken mouse and an LCD screen, I came up with the idea of making a kitchen timer. In this project the rotary encoder allows selecting the time values, the push button allows changing the states of the timer and the buzzer emits an alarm when the countdown is…
This video contains a short demo of LPG Gas Detection and Alert system base on Arduino UNO. It is synced with Blynk app which can be easily downloaded in Play Store. More info
Automatic tank filling in-home helps you automate your motor and fill the tank whenever it reaches the threshold level and turns off the motor after the tank is full. Sends you message in the process intimating you turning on and off your motor. Everything is controlled by an Arduino UNO board. More info
In this project we will control a DC motor with a smartphone via bluetooth, learning more about: DC motors Interfacing Arduino with your smartphone Bluetooth L293D IC More info
The system consists of two finish line modules and one start line module. In the finish line, you will have an Arduino UNO, nRF24L01+ Transceiver, LED button pad, photoresistors, LEDs, plastic enclosure, and tripod together with my Finish Line PCB. This module acts as the master, from the LED button pad you will decide when…
