Multiplexer: definition and applications
The multiplexer is a combinational circuit with many data inputs and selects one of them to transmit on a single output.
Optocoupler with phototransistor
The optocoupler electrically insulates a circuit’s input and output. The operation and some projects are shown in this post.
DHT11 and DHT22, temperature and humidity sensors
DHT11 and DHT22 are sensors manufactured by Aosong, with a digital output for measurements. Here, it’s shown how to use it on Arduino.
Darlington and Sziklai pairs
The Darlington and Sziklai pairs are settings with BJT transistors. The comparison between both and some circuits are shown in this post.
Digital voltmeter ammeter: how to use it?
In this post, are shown how it works and how to use the digital voltmeter ammeter. The component I bought is the DE-2645-02.
IR vehicle with Arduino
The IR vehicle is a simple project, a car with Arduino, that receives an infrared signal from a remote control to control 2 servomotors.
Arduino tutorial (Part 8, IR remote control), 2nd edition
One more Arduino tutorial. This time will be explained how to control devices with an IR remote control. The operation of IR (infrared) control will be subject to another post.
Sawtooth generator circuit
This post shows how to design a sawtooth generator circuit, or ramp, which uses a current source and the integrated circuit 555.
