I am bread boarding the circuit in the image below. However I am confused about the line going through the 555 timer. Does this mean that pins 2 and 6 are connected? Or is it just pin 2 which goes in between the two photodiodes?
Currently, the problem I am having is that the motors just stay a constant speed. Even without the connection to pin 3, they are both spin as if directly connected to the battery, unaffected by the chip. How is pin 3 even supposed to be connected? The two motors look like they are connected in series already, as if directly supplied by the battery. I am supplying the timer with power from 2 aaa batteries and the two motors are 1-3 volts each. I also have a cmos 7555 chip which I tried, it does the same thing. I am pretty sure its my wiring which is off.
Any help is much appreciated, thank you.
