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 video we will see how to make an inductive sensor for Arduino. We’ll start by looking at the electronic components we’re going to use, then step together the circuit, also explain the source code in detail, and finally test how the whole system works. You may be interested in projects in Arduino, pic, […]
In this tutorial we will use the radio frequency modules apc220 and arduino mini pro, to turn on lights or any other device, at a distance of up to one kilometer. This project is ideal for controlling devices, where there is no possibility of having internet to control them. Plates and modules used in this […]
In this tutorial we will see how to create an automatic alcohol dispenser with water, to disinfect hands. It is activated by bringing your hand closer to the reflective infrared sensor tcrt5000l, whose signal is amplified by a ua741cp operational amplifier. The output of this integrated is connected to the base of the tip42c pnp transistor, which […]
