gpio

Hi I am using the pic 16f18313 and have an LED with 220 Ohm resistor on a GPIO pin. So drawing about 15mA. I am looking to add a buzzer(active) to same pin as an audible resource if your not looking at LED. The buzzer with 82-100 Ohm resistor draws 15-18mA (measured) witch brings the current...

Hey all, I'm currently building an escape room & have decent good electronics knowledge, however, I'm on a project that has stumped me: We have an arcade machine built with a custom mini game running on a pc, the controller joystick and buttons operate via a usb decoder & are fully...

I bought a relay like this today for my raspberry pi, and I am encountering a very strange issue. I connected the 5v output to the VCC pin, the ground to ground and a GPIO pin to the IN pin on the relay. I opened python and assigned 'led' to 'LED(15)', which is very standard. THAT triggered the...

Well , I was looking for a slave addressable ic for 1 wire protocol which can control a single GPIO. The RS2413 is the most right IC I could find suiting my needs (however I need only 1 gpio). But in my country, I'm having difficulty finding this IC, also, if there is a little cost effective...

Hello! I am a Ph.D. student in particle physics and for our experiment we need to convert a 5V TTL digital signal (16-bits actually) coming out of a Phillips 726 converter and read it using the GPIO pins of a Raspberry Pi 4. We do not need bidirectional communication. We just need to read this...
