This kit contains an ultra-thin infrared remote control with 20 function keys and a 38 kHz infrared receiver module. The receiver decodes standard 38 kHz signals so you can program an Arduino to create remote control robots and interactive works.
The receiver combines a photo-detector and a preamplifier in one package, with an internal filter for the PCM frequency and improved shielding against electromagnetic interference.
The transmission distance is up to 8 m and the effective angle is 60 degrees, although the range depends on the environment and the receiver's sensitivity. The remote uses a CR2025 button battery, measures 86 x 40 x 6.5 mm and weighs 10 g. Static current is 3 to 5 microamps and dynamic current 3 to 5 mA, and the key life is 20,000 presses.
The package contains the remote, the IR receiver, three female-to-female jumper cables and an LED. To use it, connect the receiver's power, ground and signal pins to your Arduino, install an IR remote library, print the codes that each key sends and then use those codes in your sketch to switch outputs on and off.
Beginners adding remote control to a robot car, a lamp or a small display, and anyone learning how infrared communication works.
Use the 20 keys to steer a robot car, switch lights, select modes on a small display or step through a slideshow. Print the code from each key in the serial monitor first and then map those codes to actions in a switch statement. Add a short debounce so that one press does not trigger twice.
Twenty function keys.
Up to 8 m, depending on the environment.
A CR2025 button battery.
