Solved the 2nd yet ?
If not, here’s another brain challenging question ...
How can we make a circuit with 2 timeout modules, so that when the 1st timeout finishes it’s cycle (output 1 goes out ), the output of the 2nd timeout bit starts a cycle from on to off.
The circuit uses 9 bits and of course, no arduino bit
Good luck !
And oh, here’s a little video of the circuit in action ( I used 2 xtra wires to connect the led bargraph bits, they are not really needed )
