In this tutorial we will see how to assemble a gas leak detector alarm system with arduino nano. We will see a list of the electronic components to be used, the assembly of the circuit, the source code, and finally we will test the operation of the system. This project is ideal for use in […]
In this tutorial we will see how to create a weather station, for places where there is no internet access with LORA modules, GPS, Temperature and humidity sensor DHT11, but I recommend the DHT22, we will also work with an anemometer to measure the wind speed, as a controller of the system we will use […]
In this tutorial we will see how to do a synchronized radio frequency control, since one control can control the other. With APC220 modules, which according to the manufacturer can reach a distance of up to one kilometer, under appropriate conditions, are transparent radio modules, since everything that it sends through the serial port, is […]
In this tutorial we will put together a dual light ignition system, since we can control the ignition and paid by means of an infrared remote control, and also by means of 8 pushbuttons. We will use an 8-channel relay module, an arduino nano, an infrared receiver module, a pcb made of pcbway, and other […]
In this tutorial we will see how to make an automatic fish feeder with arduino nano, a 28byj-48 stepper motor with its respective controller. In addition, a real-time PSTN or clock is included, ds1307 although it also serves the ds3231, which will allow us to configure the system to do the food download at the […]
In this tutorial we will see how to make a system that allows us to turn on lights with telegram, from anywhere in the world, just by typing a command. To do this a dual channel relay module will turn on two 110V/220V bulbs, the esp32 will connect to our Wifi network and by means […]
In this tutorial we will see how to make a motion detector system, with a PIR sensor, a relay module, to connect a 110V/220V focus, an esp32 that will connect to our Wifi network and send alert notifications, by messages through the telegram messaging service, when the PIR sensor detects a movement. You may be […]
In this tutorial we will review the I2C OLED display module of 0.91 inches with the SSD1306 OLED driver of the company MakerFocus With it we will develop a small project with Arduino mino pro, a relay module, a pushbutton, the ignition of a focus. Description: MakerFocus 2-Piece I2C 0.91-inch OLED Display Module with SSD1306 […]
In this tutorial we will see how to make a rhythmic audio meter with the lm3915 integrated circuit. We will look at the list of electronic materials and components, also the assembly of the board step by step and talk about some features of the lm3915 integrated circuit. Field of application This integrated is used […]
