    Question about my halleffect sensor> transistor> LED c

    Quick question, hoping someone can point me in the right direction. I need to light up 3 x 3.3V 20mA LEDs using a 5V power source. I need to turn these LEDs (in series) on and off via a small hall effect sensor THIS ONE. That sensor says it can only output 10ma which my LED circuit draws 60...

    Set of circuits for new project - Guidance would be great!

    That was my initial thought as well however executing that to make a successful prototype seems to be way beyond my means at this point :/

    Set of circuits for new project - Guidance would be great!

    Re: Set of circuits for new project - Guidance would be grea The "charging status signal" has to be sent wirelessly, no wires can be used to transmit this signal to the corresponding LEDs, the signal only has to travel about 4 inches max. Any form of diagram you'd be willing to create for me...

    Set of circuits for new project - Guidance would be great!

    Re: Set of circuits for new project - Guidance would be grea I require a whopping 4 inches of range only. The flashlight only has to transmit its charging status while seated in its charging station, once it is removed it doesn't matter. I have no experience programming PICs, I have only...

    Set of circuits for new project - Guidance would be great!

    I am a product designer by trade an occasionally take on a project with electronic aspects, this project is by far the most complex I've attempted. In short, I am trying to wirelessly charge (inductive) a flashlight that will contain NiMH batteries, that will power 2 sets of the LEDs. The user...

    Point me in the right direction? (USB Peripheral)

    Im looking to develop a USB device that will turn 2 bicolor leds from red to green when a serial numbered entered via the computer is matched with the one stored on the usb device. I need to make 4 of the units, as inexpensive as possible, as well as create a simple piece of software to allow...

    Simple circuit qestion, NEED HELP!

    I need to wire up a simple circuit comprised of the following components. 5x Infrared LEDs 1.28v 30mA 1x preexisting IR camera/bluetooth circuit 3v 300mA My question is can I wire these up to run off of 1 of 3 ac adapter that I have? 7.5v 700mA 5.2v 650mA 5.1v 700mA If so would someone...
