If you use the timer hardware you could use Timer 1 to drive one motor and Timer 2 to drive the other (and use Timer 0 for millis() etc.). ![]() However the hardware is quite capable of doing that itself, at least to selected pins. For testing I use Wemos D1 mini R2 ESP8266 connected via USB to PC Im trying to turn on and off an LED connected to a pin on the module. This will be noticed mostly on low duty-cycle settings (e.g. The servo library appears to use interrupts to generate the pulses. This is because of interactions with the millis () and delay () functions, which share the same internal timer used to generate those PWM outputs. You do not need to call pinMode () to set the pin as an output before calling analogWrite (). ![]() Unlike the PWM pins, DAC0 and DAC1 are Digital to Analog converters, and act as true analog outputs. So I was wondering if I had any options to run a PWM continuously and then another PWM pin some of the time? I feel like there's got to be some way in code to this because this applies to all motor based projects. The Arduino DUE supports analogWrite () on pins 2 through 13, plus pins DAC0 and DAC1. However, I need the motor to be able to running all the time or it'll get stuck (bad motor). So I'm led to believe that it is an analogWrite issue cause changing my delay in between my analogWrites of the two components potentially allows them to both work. However, these PWM pins seem to limited to 3.3V as I set them to analogWrite(FanPin, 255) and digitalWrite(FanPin, HIGH) and only got 3.2-3.4 V. Various articles I've read says that the default output on a pin is 5V since this is a 5V capable board. ![]() Initially, I thought it could be a PWM timer issue but I looked up online and and documentation says all the motor pins I tried used other timers. I would like to modulate the voltage coming out of the PWM pins with a maximum of 5V. The problem I'm having is that I can only get either my motor or my servo to run, not both simultaneously.
