Arduino MQ-7 / MQ-309A ** Note **issue: MQ-7 and MQ-309 needs two different voltages for heater, they can be supplied by PWM and DC Signal controlled by your controller, another option is to use two different power sources, you should use the best option for you, next i will show...

otherwise you will get jitter in the generated PWM. E.g. wait for a formerSerial.print()statement to be finished bySerial.flush(). Since the Arduinomicros()function has a resolution of 4 µs at 16 MHz, we always see a small jitter in the signal, which seems to be OK for the rec...
The counter, frequency, and duty cycle values from the Input Capture block and duty cycle of the PWM signal from the Digital Input block are published from the Arduino board to a WebSocket server. Whereas, you can change the LED ON/OFF position and the PWM values on...
Now my intention is to connect a radio control model receiver (RX) to arduino, take the PWM signal from it, and use this signal as the input to the arduino. If I understand correctly, I would use "Standard Servo Read" block to read PWM signal from the RX. I am having trouble ...
from the potentiometer will be between 0 and 1. We know that what we can control on the PWM pin is the duty cycle of the 3.3 volt signal. We know that when the potentiometer reads 0, we want a 0% duty cycle on the PWM pin, which would have the LED off. This is our first ...
