This is a project of a vehicle with tracks controlled by a pair of RF modules and intergated circuits HT-12E (encoder) and HT-12D (decoder).
This is a project of the classic game Pong on Arduino, that shows score with horizontal rolling when finish the match.
It is possible to control a robotic arm without a microcontroller, using simple electronic circuits. This post shows how.
This is the second edition of the post about H bridge shields. It has additional information about the use of PWM on H bridge shield L298N.
The rotary encoder looks like a potentiometer, but the operation is completely different. How it works and how to use it in Arduino are today’s subjects.
The Seebeck and Peltier effects are thermoelectric phenomena that explain the operation of thermocouples, temperature sensors with 2 different materials.
The shift register is useful for increase the number of the microcontroller’s output terminals and to convert parallel binary data in serial and vice-versa.
In addition to parallel and series, impedances also can make star and delta connections. Also are shown the transformations.
This is the third and last part of the series about BJT transistor polarization. Other circuit configurations are shown.
