IR Emitter using Raspberry PICO module #15

Closed EagleZodiac007 closed 2 years ago

EagleZodiac007 commented 2 years ago

Hi Peter, I haven't get a clear picture for to setup an IR emitter using RPI PICO. RPI PICO and IR LED are enough for generating the signal or we need any external circuit or external board?

You need to use a circuit like those described here. The IR diode needs to be driven with a relatively high current which exceeds the capability of the output pins of microcontrollers.

I tried to build this https://github.com/peterhinch/micropython_ir/blob/master/TRANSMITTER.md#11-pyboard-wiring but failed. I saw this https://www.adafruit.com/product/157 and it works well to transmit. Point in fact I heard in the Adafruit video that lots' of people have struggled to build a circuit to emit IR frames "just right". I blame my rudimentary EE skills...:P and was happy to pay the $4 :)

EDIT: As nice as the Adafruit is, seems like it may not be the ideal component for a pico to pico solution https://github.com/peterhinch/micropython_ir/issues/36
