An earlier attempt to switch the lights

In this 2025 experiment, I try using an ESP8266 and a relay to switch a light circuit after identifying the remote as radio-frequency.

WHERE THIS TEST ENDED

The recorded test ends without a reliable working connection. This is an earlier experiment, not the current projector-control design.

Use a switch in the circuit

The video describes the light remote as radio-frequency rather than infrared. Instead of replaying its remote signal in this test, I try switching the circuit with a relay controlled by an ESP8266.

The intended chain is a command to the controller, a change at the relay, and power reaching the light. The remote and the relay are different ways of influencing the light; sending a command to the controller is not itself proof the light has power.

Test each connection separately

I work through an earlier cut in the wiring and try the on/off controls. The test exposes missing power and a poor connection, and it does not finish with a dependable result.

The footage mentions several supply voltages, but it does not establish a verified wiring specification. This breakdown records the experiment and its failed test, rather than presenting that wiring as a build guide.

How it differs from the current work

The 2026 projector work uses captured infrared commands and a separate transmitter. That is a later approach for a different device, not evidence that this earlier relay circuit was fixed.
