JP’s Product Pick of the Week 8/4/26 RECAP Adafruit High Power Infrared IR LED Emitter
Watch on YouTubeVideo summary
In this episode of JP's Product Pick of the Week, the host demonstrates a high power infrared (IR) LED emitter designed to send signals directly to an electronic board without needing traditional remote controls. The setup features a Circuit Playground Express microcontroller connected via alligator clip JST PH cables to a specialized IR LED board, creating a functional system capable of controlling various devices. This hardware combination allows for hands-free operation and serves as a practical example of how simple components can be integrated into larger automation projects or educational STEM activities.
The demonstration begins by pressing a specific button on the controller, which triggers the device to run through a sequence of pre-programmed codes including protocols for Sony and RCA televisions. When activated, this signal successfully turns off the top television and simultaneously switches on the bottom one, showcasing the emitter's ability to communicate with different brands using standard IR frequencies. The host notes that when no active signal is being sent from the board, a connected TV defaults to displaying a blue screen, which serves as an indicator of its listening state for incoming commands.
To further illustrate the versatility and reliability of this product, the presenter manually operates one of the televisions by clicking their physical remote control while both units are in operation. This step confirms that the IR emitter does not interfere with standard remotes but rather complements them to create a more flexible environment where devices can be toggled on or off remotely via code. The ability to turn all connected TVs off simultaneously using a single pin press highlights the efficiency of this solution for managing multiple entertainment systems from one central point.
Ultimately, the video concludes by emphasizing that this high power IR LED emitter is an excellent addition for makers and hobbyists looking to expand their control over home electronics or build custom automation setups. By bridging the gap between microcontrollers like the Circuit Playground Express and everyday appliances such as televisions, this product offers a tangible way to apply coding concepts in real-world scenarios. It stands out not just as a component but as a complete solution for those interested in exploring infrared communication technologies within their own projects.

the high power LED infrared IR emitter
send a signal to this board. It then
sends that signal to IR LEDs uh for a
moment. So, I've got a Circuit
Playground Express and then I'm using
one of our little alligator clip JST PH
cables plugged into the IR LED board.
First, I'll press this uh this second
button here. And what that one does, it
runs through a few codes, including the
Sony and the RCA code. So, this should
turn off the top TV and on the bottom TV
here. So, you can see that one when it's
got no signal. It just happens to go to
a blue screen. Um, I can turn the Sony
by itself back on again. It's just
clicking my remote and bouncing that all
around. Uh, and then I'll turn them both
off with this one pin. It is the high
power infrared IR LED emitter with STEM
PHJST
connector.
