In this project, a device will be designed which will allow controlling a servo motor from the desktop computer on USB interface. For controlling a servo motor, PWM output needs to be generated from the microcontroller. The length of the ON time of the PWM signal at the control pin of the servo determines the […]

In this project, a digital voltmeter will be designed which will show the voltage reading on a desktop application. The device will read analog voltage with respect to the ground, digitize the reading and send the reading to personal computer on USB interface. The device could read four different voltages in range from 0V to […]

Somewhere in Greece, someone did something never done before… Seen those things before? Thing: 1 Thing: 2 Thing: 3 Oh, you have! You bought one of them you say? Oh… Don’t worry, I did too. They did the job, yeah. But we paid for them much. Really much. And while our whole project would cost […]

I’ve had the HobbyKing Rattler for some time now and I’ve been making small modifications here and there which have accumulated over time and has gotten to the point where it would be nice to have everything on a custom PCB. Here’s how everything looks at the moment, pretty messy with kapton tape wrapped around […]

Open Programmer – An open source USB programmer for PIC micros, I2C-SPI-MicroWire-OneWire-UNIO EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices. Completely free and Open Source (including firmware) Programs PIC10-12-16-18-24, dsPIC30-33, EEPROMs type 24xxxx (I2C), 25xxx (SPI), 93xx6 (MicroWire), DS24xx (OneWire), 11xxx (UNIO), some ATMEL micros, communicates with generic I2C & SPI devices […]

A while ago Farnell sent email to me and offered one (inexpensive) product  as a sample in exchange for mentioning it at this blog. I browsed for a while for an interesting part and settled with Microchip MRF24WB0MA/RM WiFi module (Order code 1823142). This module is quite inexpensive and is used in products like WiShield […]

Introduction devDuino Sensor Node V 4 is a compact Arduino-compatible microcontroller and is designed to build wireless networks based on transceiver nRF24L01+. You can easily connect other sensors or actuators to this platform, to build your remote monitoring or controlling system. Unlike the version 1,2,3 is on board built-in sensor temperature and humidity. Model:103990074 Feature […]

Building our own digital clock is one of the dreamed project by most of the hobbyist or anyone that want to learn or involve seriously in the embedded system world; the ability to integrate time, day and date to the embedded system is one of the important knowledge that should be known by any embedded […]

This instructable will document and explain my latest project, a standalone computer system based upon a single chip (IC); the ATmega 1284P. The 1284P is responsible for all aspects of the system, including running the BASIC interpreter, generation RCA video signals and reading keyboard input. This computer system runs TinyBASIC just like my Arduino BASIC […]

Introduction My project uses Doppler radar sensors in order to provide the user with movement, speed, and distance information of their environment. An array of Doppler radar sensors are placed on the user�s head and vibration motors are placed on the user�s chest, neck, back, and/or arms in order to provide input to the user […]
