Summary of IR remote tester
This article describes a low-power IR remote tester circuit using a Microchip 12F683 microcontroller, an infrared receiver, and LEDs to display data levels. It operates on any infrared remote, powered by two AAA batteries with minimal current consumption (0.8mA standby, 1.2mA active). The PCB was fabricated via CNC with 0.6mm wide tracks to accommodate the SOIC package.
Parts used in the IR Remote Tester:
- Microchip 12F683 microcontroller (SOIC format)
- Infrared receiver
- LEDs for data level indication
- Two AAA batteries
- CNC-fabricated PCB
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 circuit does not require many components … just a microcontroller, an infrared receiver and some LEDs to indicate the level of data received by the remote. It works with any remote that works with infrared.
The microcontroller I used was the 12F683 from Microchip in SOIC format.
Only need 2 AAA batteries and it’s current draws is only 0.8mhA in standby and 1.2mhA in continuous detection.
Como tem sido habitual, fabriquei a pcb na minha CNC. Uma vez que decidi usar um microcontrolador em formato SOIC, as pistas mais pequenas ficaram com uma largura de apenas 0.6mm.
Aqui está uma foto do detalhe de corte das pistas com o microcontrolador em posição ainda por soldar.
As usual, the PCB was made with my CNC machine.
Since I decided to use a microcontroller in SOIC format, the smaller tracks had to be only 0.6mm wide.
