Hello friends !!! This is a special collaborative video between various youtube channels. The proposed theme is project with audio. The project I propose is to make a prototype that can help non-seers. It has two modes of operation, one that is activated with a switch, which depending on the distance will generate a more […]
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 assemble a servo tester with the legendary 555 integrated circuit. This circuit generates a PWM (pulse width modulation) pulse to be able to move a servo in one direction or another. It is a simple and didactic circuit, with very economical electronic components and easy to find […]
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 […]
