any possible answers?view story

http://forum.allaboutcircuits.com – lecturer put this as a bonus question... A current constituted of a single electron travelling through the centre of a conductor is being studied by a first year engineering student.. The conductor branches into two pathways of equal resistance 1 ohm: Path A and Path B. What do you think the voltage developed across each path should be? (Embedded)

Difference between ceramic and electrolytic capactiors?view story

http://forum.allaboutcircuits.com – Hello I'm am trying to complete some projects using the arduino and I was wondering if I am able to use electrolytic capacitors in place of ceramic capacitors? In the schematics there are cermaic capacitors and I only have electrolytic capacitors. If anyone could tell me if my projects will still work with my capacitors and what the difference is that would be great. Thanks in advance!! (Embedded)

Analog Sensor with digital input?view story

http://forum.allaboutcircuits.com – I have a TI cc2540 to which I would like to attach a variety of photoresistors. The cells resistance decreases with light intensity. I would like to trigger a specific action when the resistance decreases past a certain threshold. I am already using the analog inputs on the device for other purposes. (Embedded)

bcd to 16 segment (hex) decoderview story

http://forum.allaboutcircuits.com – Hi all! i just learnt that there is an IC that is a BCD to 7 segment display decoder. it is called "DM7442A BCD to Decimal decoder." I am looking for an IC that can be a bcd to 16 segment (hex) decoder. do they make such ICs? can you give me a generic number for it? thank you. (Embedded)
