How did you determine the resistance for the pull down resistors? Why can't you use a resistor with a value of 10k ohm? How did you determine to use 1k ohm resistors?

9 volt battery is also work in this project?

Hmmm, mine doesn't do what it was designed for. . I think it's becuase I swapped to using on 470ohm and my 1k are all really close to each other. And they are so small they look like smd resistors with small little leads hooked up to them

Where did you get those dip switches with the base so they won't move?

Gracias - El video mio se encuentra en el YOU TUBE y se llama -
Robotizado con CD 4017, NE 555 Pilotos
El plano esta bajo el video.
Con esto funciona mucha maquineria solo.
Cuidado de poner un condensador de 10 nF en el conextor 5
de cada NE 555 hacia el negativo.
Con esto giran los motores con exactitud.
A parte el dibujo con el puente H -
El motor debe estar conectado en el emisor y no en la base
de los dos transistores. Andre Troll Kaiser - alemania - sajonia-
