Right-left scrolling LEDs
Posted on: 11 Nov 2016
Project description: In this project, 8 LEDs are connected to PORT B of a PIC microcontroller. Also a push-button switch is connected to bit 0 of PORT A using a pull-up resistor.. When the switch is pressed the LEDs scroll to the right. Hardware: The circuit diagram of the project is shown in Figure 1. […]
Tiny audio amp produces 1.9 W from 5 V
Posted on: 11 Nov 2016
Description The PAM8905 is a high efficiency Class – D audio power amplifier with an integrated boost converter. It drives up to 1.9 W (1% THD+N) into a n 8Ω speaker. With 85 % typical efficiency, the PAM8905 helps extend battery life when playing audio. The b uilt – in boost converter generates the voltage […]
Portable GPS Data Logger
Posted on: 11 Nov 2016
I have built a GPS Logger and it works very well to trace the drove route for two years. By the way, the navigation solution computed by GPS receiver itself has an excellent accuracy without DGPS because an intentional offset added by US goverment has been stopped several years ago. The position error seems to […]
PC Interfacing a GameBoy Camera using PIC18F4620 microcontroller
Posted on: 11 Nov 2016
PC Interfacing a GameBoy Camera Here’s another past project of mine from a couple of years ago. At that time I was looking for a low-res camera for simple robotics image processing, and all I had experience with was PIC (12, 16, and 18) microcontrollers. So I didn’t really get to work on the images real time (not enough […]
Servomotor-based mobile robot control
Posted on: 10 Nov 2016
Project description: Mobile robots are used in many industrial, commercial, research, and hobby applications. This project is about the control of a mobile robot using servomotors. The robot used in this project is the base of a popular mobile robot known as Boe Bot, developed by Parallax (www.parallax.com and www.stampinclass.com). The basic robot is controlled […]
How-to: USB remote control receiver using pic microcontoller
Posted on: 10 Nov 2016
ow that we listen to MP3s, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you’re probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from […]
Door lock opener
Posted on: 10 Nov 2016
description This circuit can be used to operate an electric strike or an electromagnetic lock on a door. It is not the door being opened/closed, but a small electromagnetic strike which unlocks the door. The opener has the following features currently programmed in software: automatic operation when a guest pushes the doorbell, the strike is […]
HARDWARE MAKERS
Posted on: 10 Nov 2016
This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current sense output gives the value of the […]
