About ARDUINOPWM pin Frequency control output
Board: Arduino M0 Pro Zero
Use Tone (pin_led_13, 1000); /* Change Current PIN frequency */
Use Analogwrite (pin_led_13, 200);/* Output PWM waveform */
The principle is that the tone function changes the Prescaler value of the clock domain, causing the PWM output waveform frequency to change
Minor adjustments can change the count upper value in the Analogwrite function prototype

This session uses the Arduino mega or Genuino Mega board to allow 12 LEDs to be dimmed one after the other. The reason for using Mega is because it has more pins that support PWM operations.

Buy MPU6050 self-contained attitude solver greatly reduces the work done by the upper processor. By getting acquainted with the processing after doing a small example is to feel the magic of this sensor. Arduino sectionThe main is to read MPU6050 data and the acquisition of Euler angle through the serial port printing to the host computer, the acquisition of data is very simple, MPU6050 received the Arduino

Android adk with a standard Arduino UNO and USB Host shield a few weeks have past since my last post and a lot was going on. First off how great was Google io? I Hadn't the chance to participant ipate personally but I watched a lot of sessions online and was amazed of what Google had up its sleeve. new APIs, services, best programming practices but most importantly a lot of great talks about Android. as a software and hardware tinkerer I was gglad to

Arduino can be used to develop completed electronic components such as switch or sensors or other controllers, LEDs, stepper motors or other output devices. Arduino can also operate independently as an interface that can communicate with software, such as flash, processing, MAX/MSP, VVVV, or other interactive software .... The Arduino development IDE interface is

This time, we will use Arduino and a set of three-color lamps (red, yellow, and green) to Apply PWM. First, let's take a look at the Arduino board. There are six PWM interfaces in total, they are digital interfaces 3, 5, 6, 9, 10, and 11. For convenience, we use the continuous PWM interfaces 9, 10, and 11. During program writing, we wi

The role of version Serial.flush () prior to arduino1.0 is to empty the serial cache (dropping received incoming data). But after 1.0 the function of version Serial.flush () is adjusted in order to wait for the serial port data to be transmitted (Waits for the transmission of outgoing Serial data to complete.) (Referenced from http:// Arduino.cc/en/serial/flush).Because I am in the process of using Wifibee, if both want to use serial.print through the serial port to the WiFi module to send instr
