Using the MSP430 LaunchPad in an easy way
In this post I will show a different microcontroller. The MSP430 Launchpad is an alternative to Arduino.
Arduino tutorial (Part 4, random numbers)
In this forth part of Arduino tutorial, I will show how to use random commands to generate random numbers. One of the applications is to control devices randomly.
H bridge
If you want to build a vehicle or a mobile robot with wheels or mats, you will need a H bridge, a circuit which controls the two directions of a…
Pulse Width Modulation (PWM)
I will talk about what is pulse width modulation (PWM), how this technology is useful to electronics and robotics projects and how to use it.
Arduino tutorial (Part 3)
In the third part of this tutorial, I will show how to use servomotors and new commands. This post has been updated.
Arduino tutorial (Part 2)
The second part of Arduino tutorial series will show how to implement digital inputs, use buttons, and analog inputs to use sensors. Click in the following button to see the…
Arduino tutorial (Part 1)
This post is part from a series of posts about how to use Arduino. It is a very easy microcontroller to learn and you can do many projects.
Resistance, Capacitance, Inductance, Impedance and Reactance
This is another post about basic concepts of electricity. This time I will talk about resistors, capacitors, inductors in CC and AC.
NTC and PTC
Just like you can build light resistive sensors, it is possible to build temperature resistive sensors. There are many types of temperature transducers, in this post I will talk just…
