Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR) – Second Part

One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot – First Part) and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the microcontroller for the Lin ...

Basic Servo Motor Controlling with Microchip PIC Microcontroller

The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm for this servo motor. The servo motor basically is a high quality geared DC motor equipped ...

OH HAI! on Windows 10 IoT Core

Story Oh, Hai Hai ('hi') is an integration point for several stand alone smart home technologies.  Hai runs on the Raspberry Pi and can be adapted to optimize electricity consumption (lighting/HVAC) and water usage (irrigation/rain collection) in a number of ways. Hai was originally envisioned for any Pi running Raspbian OS, but is also being ported over to utilize the new Windows IoT Core on a Raspberry Pi ...

Cellular Data Logger

Story I have been collecting data from Raleigh's trails and parks for the last couple years.  My primary platform has been a custom Arduino board I developed for low-cost (hey, these things may get damaged or stolen) and long battery life.  I wanted a connected sensor to provide current data and, after looking at various technologies, I have settled on cellular as the most convenient.  This sensor uses an o ...

Physical computing with ATtiny

Story I have a nice "carranca" (or wall mask) from Chile that stands in my corridor. It's a very beautiful decorative mask that I liked from the very first moment I saw it at the shop. Few weeks ago I wondered if I could bring it to life by adding a motion sensor and some lights in it, since it has three convenient holes (two for the eyes and one for the mouth) and enough space on the back for housing wires ...
