I know that a single 555 chip can be used to control a fuel injector with inputs from a hall sensor and a pot to act as a simple fuel injection controller to run an engine. But what im wondering is if it is possible to use multiple chips so that they can feed the one another so that more sensors could be used ? Say one 555 with a pot as a throttle position, a hall sensor for a trigger, then feeding into another 555 with a temp sensor, then that 555 feeding into a 3rd 555 with a barometer? I know it would be a pain to tune, but would it work? Sorry if this simple, I'm new to using ic chips.
