BILLINGS PRO RUN CONCURRENT TIMERS HOW TO
The only thing I know that is less than optimal is running two loops one after another but I don’t know how to merge them together and still retain flexibility in setting how long on and off stages should be for each of them separately.
BILLINGS PRO RUN CONCURRENT TIMERS CODE
I’m not sure if I’m doing anything wrong with my code though. Both motors are 12V so 8.5V I get at PWM=255 is quite enough to run them (I confirmed this using the benchtop DC power supply).
I have Arduino powered by a 9V DC power supply. I cannot see anything wrong when I try to debug it via Serial.println(), it’s directly on pins A and B where I see the issue (I’m using a multimeter), i.e. However, when I try to make them asynchronous, the equipment will run once and then either one of them will stop, or both, or one or both cycles will go awry so they will run at their own pace. I tested this extensively and I found out that all works very well when the cycles are synchronized or when the shorter cycle fits N times into the longer cycle (N is a whole number). The way I’m doing it is shown in the code below. I’m using millis() instead of delay() because of this reason.
I’m trying to run a motor and a pump concurrently but also to cycle them on and off separately.
