The TK15 at an angle: a black board with a gold border, a steel box with an X-shaped window lying flat near the top and its three legs running down to three holes, an LED and a resistor at the top right, lonely binary and IR RECEIVER along the left edge, two big mounting holes, and a right-angle four-pin header labelled GND, VCC, NC and SIGNAL.

IR Receiver

A Vishay TSOP18138 38 kHz infrared receiver on a TinkerBlock board: SIGNAL idles HIGH and goes LOW while a remote sends, and the IRremote library turns those lows into an address and a command.

Tuned to: 38kHz
VCC: 2.0–5.5V, to match your board
SIGNAL: LOWwhile a remote sends
Sees: ±45degrees off axis

Turn it over and see the three holes to wire: GND, VCC and SIGNAL. SIGNAL idles at VCC and drops LOW while a remote sends, so match VCC to your board.

Take it with you

Point a phone camera at the code and this page opens there. It is the same address as the one printed on your box, so it is also what to show someone you are passing the board to.
