I am currently experimenting with a single microcontroller powering up a number of LEDs.
There are still yet more LEDs but as they are supposed to be on all the time, they are connected directly to the main via a resistor without utilizing the microcontroller pins.
It seems to me that every now and then the PIC will fail to work, probably because there are just too many LEDs driven by this 4.5 volt battery.
But then the funny thing is, sometimes when I plug on and off the decoupling capacitors from the breadboard, the whole thing will work again.
I have tested this with a number of my spare chips, they all behave the same way, so unless they are ALL damaged I have to believe this bogs down to two main things.
First the LEDs connected directly to the battery drains its power too quickly and the Chip failed to receive the required power soon.
Second…since removing and replacing the decouple 0.1uf capacitor works [sometimes], it must be the mysterious “noise” that people talk about when they talk about experimenting with Breadboards.
This is a really exciting time for me to ask.
So…what really is this “Breadboard Noise” thingy ?
This event got me really interested in it
