April 25, 2020 by Jawad Hasan Shani. Continuing from my previous post on sensors, in this post, I will write about how to do analog-read from Arduino. We will use a photo-cell (also called photo-resistor, LDR etc) for our demo purposes. I am using Atmega328 with arduino bootloader.

Jag har kod som gör SPWM för en 3-fas inverter online. Jag applicerade sedan en programvara  Jag har velat bygga strömsnålt och låter den lilla Arduino Pron gå ner i vila i två float volts = (analogRead(A0) * 4.16)/902; //4.16 = Volt för fullladdat batteri. Joystick Arduino - Anslutning och skiss.

Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023.

100uF on TL431 output. 1uF on A0 input. I also increased the sampling rate to 128 times (and removed the delay). Here's the result, as accurate as my multimeter: There's still 2mV difference in higher voltages which is because of my 2.5V reference voltage and Arduino ADC 10bit resolution (2.5 / 1024 = 0.002).

The RC filters are implemented The board has the same design for PA6/PA7 pins (doesn't work from Arduino) and PB0/PB1 (works from Arduino). All four pins are designed for a thermistor 10k usage. I've tried to use pinMode with output and output_analog - without any success. Plus PB0/PB1 works without pinMode (as it should be for analogRead).
