DDSFreqGenProto

Another DIY function generator using PIC16F628

An extremely simple and low-cost Sine/Square wave generator, known as the “Custom Function Generator,” is developed based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip.. The frequency can be set for any frequency from 1Hz to 10MHz in 1Hz resolution steps! All this with three push buttons and a novel “sliding window” […]

Shift Register

How to use a 74HC595 Shift Register with a AVR ATtiny13

Intro: How to use a 74HC595 Shift Register with a AVR ATtiny13 If you have been playing with microcontrollers and electronics then you have likely seen LED dot matrix displays and other projects that use shift registers like 7-segment displays and more. This instructable goes over a quick intro to the 74HC595 8-Bit Serail to […]

RFM12 Wireless Transceiver Module Demo

RFM12 – Wireless Transceiver Module Demo using pic microcontoller

Description Hardware Software Running the RFM12 Demo Download Links Description This project shows how to do wireless communication with the RFM12 tranceiver modue in combination with a PIC microcontroller. The RFM12 is a low costing ISM band FSK transceiver module. There are different module variants available which support different frequency bands: 315/433/868/915MHZ. The module has […]

PIC16F630

Wireless 10 channel receiver using PIC16F630

This project can steer 10 different things wireless with the use of a normal TV-remote-control with the RC5 protocol, from manufacters like Philips, Grundig and Marantz. If the Proton PIC Basic compiler is available, then you can ofcourse change the number of channels. Use it as follows: When ‘TV’ mode is selected on your remote-control, […]

Temperature regulator

DS1820 Temperature regulator using PIC16F628

This simple project uses a Dallas DS1820 one wire temperature sensor and a pic 16f628 microprocessor. A simple temperature regulator where a LED symbolizes the Fan. Data derived from the DS18s20 is a 9bit centigrade temperature measurement. As mentioned the temperature sensor communicates over a one Wire bus that requires only one data line and ground for […]

Schematic of BASIC Computer

$15.00 BASIC Computer using PIC32MX1 microcontroller

$15.00 BASIC Computer? Imagine a microcontroller that you can connect a serial terminal up to to get an ok prompt? What would happen if you changed one of the control registers can I see the effect straight away? Is it really possible to download programs onto this chip from the Internet and run them? Can […]

How to Wire a PIC Microcontroller

How to Wire a PIC Microcontroller?

I’m completely new to the world of PIC Microcontrollers and electrical engineering so please go easy Anyway, I managed to program my PIC 16f627 to turn on three LEDs when push button (trigger button) is pressed and start a shut down sequence (basically each LED toggles off one after another with a 5 second delay […]

LCD serial

WEBSD using PIC24F microcontroller

WEBSD This is a development board for the PIC24F series of microchip, with: USB ( plug it to any computer) Ethernet ( plug it to the internet) SD card ( save and read all data you will need) I developed this thing as a learning platform, it worked ( still is). So if you always want to go […]

Control AC load with microcontroller schematic

Control AC load with microcontroller.

As per the title of this question i’m trying to control an ac resistive load. So far i had little success and i’m experiencing “strange”, to me at least, behaviour from the triac(s) i tried. first of all i post a schematic of my test circuit (bare with it, it’s not a complete schematic, it […]
