IR Tracking Turret with PIC and C

This is a good learning project that is fun to build - I got a lot out of making it. I think this has been done quite a bit already, but I did not find a straightforward way of doing this with PICs. When I finally got it working, I thought I'd share it. It might be useful for someone that wants to learn or apply I2C, Interrupts and Callbacks, PWM, or Servo Control. Basic Functionality Detects and tracks an ...

Half Bridge Driver based on IR2104

This Half-bridge driver based on IR2104 gate driver IC and N channel Dpak  MOSFET  , The IR2104 is a  high voltage, high speed power MOSFET driver with independent high and low side referenced output channels. HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard COMOS or LSTTL output, down to 3.3V logic. A gate IR2104 driver is a powe ...

IR remote tester

O circuito não necessita de muitos componentes...basta um microcontrolador, um receptor de infravermelhos e alguns leds para indicarem o nível de dados recebidos pelo comando. Funciona com qualquer comando desde que seja infra-vermelhos. O microcontrolador que usei foi o 12F683 da Microchip em formato SOIC. Apenas precisa de 2 pilhas AAA e consome apenas 0.8mhA em standby e 1.2mhA em detecção contínua. The ...

Infrared IR Sensor Interface with PIC18F4550 Microcontroller

IR Sensor Interface with PIC18F4550 In my previous project we have made a simple IR sensor Circuit. In this project, as promised before – we are going to demonstrate a PIC18F4550 microcontroller interface to IR sensor circuit. We are just going to glow few on the pic18f4550 as an example, however you can do some more intelligent operations by adding some more logics to the microcontroller coding. Interfacin ...

8 Channel IR Remote Control

This IR remote control that you can use to control other devices or circuits up to 8 devices. The control codes are sent in RC5 format modulated to about 38 kHz carrier frequency.The IR transmitter powered by the CR2016 which is a 3V button Cells Battery CR2016.To extend the life of the battery this is done by putting the CPU into SLEEP mode for most of the time and wake-up only when a key is pressed. PIC16 ...

Crossed IR Beam Camera/Flash Trigger

This device will trigger a camera or flash unit to automatically take a picture when an object (target) enters a specific location. It uses two, crossed infrared light beams to detect the presence of the target and close a relay that trips the camera or flash unit. Response time is about 2 ms from detection to relay closure, so if your camera doesn't have long shutter-lag, it will capture even fast moving t ...

IR-Sensor Circuit and Interfacing with PIC Microcontroller

An IR sensor is an electronic device, that produces in order to detect some parts of the environs. An infrared sensor can measure the heat of an object as well as detects the motion. These sensors are used to measure only IR radiation, rather than producing it that is called as a passive infrared sensor. Generally in the IR spectrum, all the surrounding objects generate different form of thermal radiation.T ...

IR Proximity Motor Control using PIC18F4520

Infrared proximity sensors are very fun to play with. In the past we have used them to make Digital Theremins and Control Robots, always using its proximity sensing (how far away an object is from the sensor) as the main feature. Today, we're going on a quest to use an infrared proximity sensor, to control the speed of a DC motor. In this article, we will go step-by-step through the process of understanding ...
