Issue with a 12v switch via GPIO output

I am a beginner when it comes to electronics so I would appreciate your help with a simple project I am working on and have been struggling with for several days. The idea is that I have a PIR Sensor outputting to GPIO 24 on my Pi. Via a python…

Driving a WS2815 (12V, addressable) LED strip

I am trying to plan what I need to drive a 12V addressable LED strip with the Raspberry Pi (4, likely, or zero, but I want Ethernet connectivity). I am not sure I understand the WS2815 datasheet (PDF) as I am not knowledgeable in electronics. Pages…

Power MOSFET Driving Big Motor Problem

I am using the power MOSFET IRF504N. I am not sure if my Rpi's GPIO 3V3 signal can directly input to the gate of the MOSFET which requires 4V minimum. I guess that I don't need a gate driver to shift up the Rpi's 3V3 signal. So I am now…

Which of those listed logic level MOSFET to choose for driving a heater

I'm planning to control 3 LEDs and a heating element (5 Ohms) using a Raspberry Pi. The main power supply outputs 12V & 5A. Using an L78S05CV Voltage regulator, I'm planning to power the RPi. So far I didn't decide how I'm gonna power the heating…

Choosing a transistor/mosfet in order to drive Peltier element from a RPI zero

I just found these two (1,2) low power consuming Peltier elements that I would like to include them to my project. What I'm planning to do is to drive them until to reach some specific temperature e.g 60-90 Celcius (using some kind of PID). Since…

IRF530, can I put LED+resistor on input?

Can someone tell me if the following circuit is sane? It's a fairly standard lowside switch, but I've added an LED plus resistor. V_GS on an IRF530 is about 2v, so I assume that a small LED won't lead to excessive voltage drop. If that's not okay,…

Detect if a raspberry zero is turned on

I would like to use an old raspberry zero 1.3 to share files in my home network, but I wish I could shut down the connected hard drives as the system shuts down. Initially I thought that it was enough to associate the status of the ACT led to a GPIO…

Heatbed module control with Raspberry Pi 3+

I want to control a nichrome wire with the PWM signal from a Raspberry Pi. The MOSFET modules that can be found on the net for the combination with a Raspberry became much too hot. So I decided to try a heatbed module from Lerdge for 3D printers,…

LED always on while using FET

I want to switch on/off some LEDs on a breadboard using my Raspberry PI (RPi) 4. Before connecting with my RPi, I've tried to do some experiments with using a BS270 FET in an old-fashioned "dumb" circuit. Layout is a simple serial circut: 3V source…

Driving 6 electric channels on/off and voltage (48A / 30-41V) from pi

I would like from a pi, to drive a current of 48A and regulate voltage between 30-41V (1440-1968W !). Furthermore, this current will be split into 6 input, and I would like to be able to switch on/off those 6 outputs independently. Do you recommend…
