    5v/12vdc inputs and only one of those as outputs using PIC18fxxxx

    Hey all I am trying to find an **IC** that can accommodate having 2 inputs but only one output depending on what I send via a **PIC18fxxxx** micro controller. This sounds like it would be a **DPST** but I can't really find anything like that I can control from a PIC to choose what output needs...

    Using 3 Channel Video Switcher Module with Arduino

    Hey all I am wondering how to go about switch from camera 1, 2 or 3 using this 3 Channel Video Switcher Module on ebay here. Since there's only V+, V- and signal for the "switch" it looks to take a PWM but I am not quite sure if that's correct or not. If correct then how would I (in code)...

    Custom USB 7 port hub PCB dasiy-chain

    Hey all I had a schematic laid out for a custom USB 2.0 7 port hub I needed to create for a project of mine. It currently uses Ethernet RJ45 sockets to provide power and data to each hub (2 Ethernet ports for upstream and downstream USB) along with the needed resisters/regulators/etc. Though I...

    Arduino turning a knob left and right with Digital PWM

    Hey all i am trying to find a way in order to turn an car amp's bass level knob left and right using an arduino's Digital PWM pin. I am thinking that a stepper motor would be the correct motor to use in order to do this or no? Also, would there be a better fitting motor to do what i am looking...
