Infrared Emitter Transmitter Module w/ 38K Carrier Circuit for Arduino
This is infrared transmitter module based on NE555. 38KHz carrier circuit is produced by the NE555£¬ no MCU's PWM pins£¬ reduce the corresponding codes and the burden for MCU. When SIG module pin is at high level£¬ the module will send an infrared signal of 38KHz. When SIG pin is at low level£¬ the module will stop sending infrared signal; The usage is very simple£¬ so the ordinary MCU can be also used to easily produce infrared remote control projects. Features: - Compatibility: Arduino UNO R3 / Arduino Mega2560 and other microcontroller board - Operating voltage: 4.5 ~ 5.5V DC - Operating current: 50mA (max) - Emission angle: 45 degrees - SIG pin current: High lelel 0.4mA (max)£¬ low level 1.4mA (max) - You can manually adjust the direction of the launch tube according to the actual application requirements - Great for infrared remote control projects
