Hi.
Here I have 2 555 monostable circuits, the first with time 2x and the second with time x, connected in cascaded form, the output of the first timer is the voltage supply of the second one.. I'm using this circuit with a relay to let a dc motor run for time x in a direction and then it turns in the opposite direction for time x...etc.
It could not work because the circuit's supply voltage is 6V, the output of the first timer is 5 with no load, when it is connected to the other part of the circuit as a supply voltage, it drops to about 3V or less, this makes the second 555 timer not working properly, and its output useless...
I tried using transistors such as BC337 and BC548 (common emitter and common collector) with base connected to the output, collector/emitter connected to 6V/load... but this didn't rise the voltage as it should be
Any idea
