The MPU6050 module is an accelerometer and gyroscope with 6 axis degrees of freedom. In this post, are shown the operation and a project example.
In this post, are shown 2 circuit projects: an AC voltage detector and a cooler with LED effect.
In this post, are shown how to use Arduino with the TM1637 module, a 7-segment display with 4 digits and 3 project examples.
The current sources are electronic circuits that provide a constant current. In this post, are shown some examples.
This is the post’s second edition. It’s shown one more project to control servomotors with a joystick, using another method.
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.
