Hi, am new to this forum and need suggestions for the following issue-
Am using NE555P in astable mode. cap is 1uf. resistor between 6&7 is 570kohm and between 7&8 is 1kohm.
LED is blinking fine. But i want to run 2 motors. Now forget 2 motors,even one is not working. My battery is 9volt.
If am increasing the input volt by giving arnd 15volt, motor is running continuously and its not stopping at intervals.
The Dc motor am using is one i purchased from a local electronics shop and is without specifications.
When am checking the voltage and current across Dc motor by connecting it directly to battery(when its running),
voltage shown is 3.2 volt and current is .6amp. so i guess motor is not getting sufficient current at point 3 of timer IC.
Could someone plz suggest me how to work out this situation. I have copied the schematic from some existing thread as
was not able to make one to post here.
Also i tried using BC548 transistor as switch by giving point 3 output to base, emitter grounded and collector connected to
supply.but still motor is not running.
awaiting suggestions and guidence.
