The Arduino has no true analogue output pins. 0 looked even more appealing. onsemi. It has PWM pins instead. Arduino and others are moving towards 32 bit MCU devices, including ARM Cortex based platforms such as the Arduino Due, which brings significantly more resource into play, but these platforms will require a major re-education of users, and may actually fragment the Arduino user group. プログラムのあたりが難しくてよく理解できていないです。 Search and download open source project / source codes from CodeForge. Note that I used a digital voltmeter connected to pin 8 (Va output) to monitor the output and I sent commands over SPI using an Arduino UNO. Timing to generate a regular sample is provided by Timer 3. The PICkit Serial Analyzer provides the SPI master mode serial communications and power for the PICkit™ Serial SPI Demo Board. Portanto é preciso um intervalo de tempo entre o envio de um valor e de outro. Anyway, it costs less than a half of the price of the Arduino Uno, and it has the same headers too, so in case you happen to be running low on money and actually think going with something slightly nicer than just a simple 8bit micro, I guess this might be the choice for you. The precision of this ADC is similar to that of an Arduino Uno, and with 8 channels you can read quite a few analog signals from the Pi
