2019年12月10日 — Choosing NPN BJT as a switch for RPI to control motor by PWM ... you'd need to feed 300mA into its base - the Pi's GPIO can't provide that current, ... You don't really want to drive more than 6mA out of a Raspberry GPIO. ,2020年2月1日 — ... something bad happening when the pi is turned on. When first turned on, most GPIOs are inputs, some have 50k pull-downs activated, and ... ,It would be best if you provided current limiting for the GPIO port. It depends on the current gain of the NPN transistor, but at minimum a 200Ω series resistor from ... ,2020年2月6日 — Based on the descriptions, the left side shows what is probably inside these receivers. The first diagram that uses the "NPN" is safer than the ... ,2018年3月16日 — When I connected this to an input on my Raspberry Pi I was able to read the high-level, but the low-level did not register as low. Is there anything ... ,2013年2月22日 — Hi, I am trying to make a simple circuit with a standard NPN transistor. I would simply like to make an LED light up when a voltage is applied at ... ,The Raspberry Pi's GPIO pins are only capable of supplying a low amount of power. If you try to power a ...
