Learn how to make a MP3 player using ESP32, MP3 player module, Micro SD Card, and speaker. how to program ESP32 yo play, pause, next, previous songs. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided
It's time we took a fresh look at infrared remote controls, so here is everything you need to know about using IR remote controls with microcontrollers. Learn how to receive, decode and send IR signals, including ones from those hard-to-decode remotes like air conditioners. Examples with ...
2017 June 2: “Emme: A New Robot Based on ESP-WROOM-32” Kickstarter Stephen Heppell Learnometer Project purpose: Monitor your classroom environment for factors that hinder learning. Photo of bare board tinyFab TF01EINKV1 Circuit board under development that employs ESP32 for smart home use....

IO_IR_CUT: {"T":80,"status":1} It is used to control the high and low levels of the IO5 pin on the driver board, which can be used to control the night vision function switch of the infrared camera and can also be used to control the relay. ...
即使在最好的情况下(Ir=10 欧姆),这也意味着内阻会消耗可用 3V 电压中的(U=I*R,0.3A*10ohm=)3V。 换句话说,当 ESP32 启动时,它会从不良的 CR2032 中拉出大量电流,导致电压完全降至零,从而ESP32 复位/崩溃。 可以看到就是到了300mA以上的电流,应该就是峰值了 ...
