The IR vehicle is a simple project, a car with Arduino, that receives an infrared signal from a remote control to control 2 servomotors.
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.
This post shows how to design a sawtooth generator circuit, or ramp, which uses a current source and the integrated circuit 555.
This post’s subject is the LCD Keypad module, which allows to control a LCD display with buttons without wires and a protoboard.
The two shown projects to make LED effect using the Johnson counter 4017.
In this post, it’s shown how to control an Arduino with a smartphone using an easy method, through a Bluetooth module HC-05 or HC-06.
The common base is little known configuration for amplifiers using BJT. This type is used in high frequencies.
In this post, it is shown another type of amplifier configuration using BJT. This time, it is the common collector or emitter follower.
In this post, it is shown how to design a BJT amplifier with voltage divider on common emitter mode. Two examples of projects are presented.
In this post are shown 2 digital electronics projects, using DIP integrated circuits: luminous effect with 74HC595 and a semaphore.
