Ok in my circuit i simply have a 555 timer which makes an LED blink on and off I have a regulated input voltage (from an LM137) at 6volts coming into the 555. now two questions 1. why? 2. is there a way to prevent the following.
Between the Circuit (on the breadboard) and the output from the LM317, I placed a DC motor i pulled out from an old cd player, now the 555 goes weird I measure the voltage and it sticks at 6v according to the voltage meter but the LED flashing rate has gone from 350ms (1/4 or so a second flash rate) to about 10ms constantly flashing...
I tried placing a cap 440uf across -/+ of the IC i even wired up my own large inductance coil to try and filter out the voltage to see if that's causing the problem obviously there's a voltage ripple from the DC motor but the meter says it does not as in a constant 6v before/after placing the motor on, i don't need to fix this I'm curious as to why this happens and what would be needed to stop it....
