I'm not very experienced in this area so please excuse my terminology. I'm aware that a 555 chip would be ideal for creating a 12v pulse, but I cannot find one on any of the circuit boards I have lying around. I did, however find an 8 pin chip labeled ICE 2BS01. This is what I could find for a pinout (see photo). I already have a 12v and a 5v power supply. If 5v is necessary, I can just add a relay. This would not be an issue. I also have various capacitors and resistors, so I'm sure I'll have everything I need if this chip will work. I am trying to make a 12v square wave to pulse a fuel injector while it is in an ultrasonic jewelry cleaner, so 250-500hz and a 50% duty cycle would be ideal.
Oh my bad...I thought since it said general electronics that anything goes. Can someone help me out anyway? I'd really appreciate it. I don't even need a schematic, but just a simple yes or no as to whether or not this can be done. Wouldn't mind a schematic though, or at least a link to a forum that would be willing to help me. I've been considering looking in to an Arduino, but being shunned from the forum like this is a bit discouraging...
Excuse me if I'm wrong, but it didn't take me long to find this thread that has no mention of an Arduino...just a general electronics question that could be applied to an Arduino, as could mine...what gives?
Sorry, didn't want to scare you away like that.
I just think that we should keep general non-Arduino questions out of an Arduino funded forum.
The other poster already having a history of using Arduinos could have made a difference (this is your first post).
The ICE2BS01G seems to be a switchmode power supply driver chip.
Seems not suitable for 500Hz 50% PWM.
A 555 would indead be easy, and also gives a reasonable drive current if needed.
An Arduino can also generate a 500Hz square wave with just two or thee lines of code
A simple transistor with a couple of resistors could change that 5volt signal into a 12volt signal.
Leo..
Ok that's understandable. One more quick question if I may. Would a cheap alarm clock be a good place to find a 555 chip? I've read that 555's are pretty outdated and most things now use surface mounted components. I have an alarm clock here that's probably 15 years old that I never use. Is it worth tearing into?
