A Self-Contained Data Logging Anemometer

I love collecting and analyzing data.  I also love building electronic gadgets.  A year ago when I discovered the Arduino products, I immediately thought, "I'd like to collect environmental data."  It was a windy day in Portland, OR, so I decided to capture wind data.  I looked at some of the instructables for anemometers and found them quite useful, but needed to make some engineering changes. First, I wan ...

IC-Based H-Bridge Tutorial

An alternative to using a transistorized H-Bridge circuit is the L298 Dual Full-Bridge Driver. It is very easy to control and it doesn’t require any calculation. Simply knowing your motor’s required current and the IC’s current capacity is enough. For a price though.In order to learn this, you need to first download the IC’s datasheet file. Simply google “L298 Datasheet” or click the link —> L298 Datashe ...

Laser show for poor man using PIC18F1220 microcontroller

Laser show for poor man Here's another useless but cool looking "must build" gadget for every romantic geek. Let me introduce PIC microcontroller based three axis laser spirograph. Step 1 Gathering stuff Design is quite simple and employs regular parts and components but you are free to change/modify it in way you like. At first prototype I used blank DVD as reflective material but later I discovered more p ...

Building A Robot: Motor Control

Since we now have a beautiful robotic chassis, we're ready to continue our Building A Robot series, and get serious with some motor control. This second part of building a robot is perhaps the most crucial as it will define what type of control we will have over the motors. Ideally, we want a simple method for controlling the motors so that our software is free to do other things. In this article we will mo ...

PIC18 Pulse Width Modulation (PWM) DC Motor Speed Controller with the RPM Counter Project

Equipped with sophisticated Enhanced Capture/Compare/PWM (ECCP) peripheral the Microchip PIC18F14K50 microcontroller could produce up to four PWM channels output. The enhanced PWM (Pulse Width Modulation) mode in ECCP peripheral is capable to drive the full bridge DC Motor circuit directly both in forward or reverse direction. It also could generate single PWM output on the selectable PIC18F14K50 pins when ...

PIC16F84A discolight effect with bass beat control

Introduction External circuit converts bass beat of music into pulses.The motor is controlled by them. If theres bass beat recognised then the motor rotates one direction(in full stepping) for a predefined time then stops. If the second beat comes in then it rotates again for the same time and so on.There is a random number generator (from 1 to 4) written into the code which tells how many times have the mo ...

PIC 18F4550 Motor Controller Video Project

In this video, we cover how to breadboard and write the firmware for a motor controller (controlling a servo, 2 DC motors, and a stepper) with the PIC 18F4550. A few notes on this video: -I recorded most of the video during the evening of July 4th here in the U.S., there were fireworks going off in the background during most of the video. Also, there was a thunder storm at the beginning. I hope this does no ...
