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 Under the X:\XXX\

Description Reads the value from the specified analog pin. the Arduino board contains a 6 channel (8 channels on the mini and nano, 16 on the mega), 10-bit analog to digital converter. this means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. this yields a resolution between readings of: 5 V/1024 units or ,. 0049 Volts (4.9 mV) per unit. the input range and resolution can be changed using analogreference

SI7021 is a temperature and humidity sensor chip produced by Silicon Labs. Its main features: Humidity accuracy: Error typ. +/-2%RH, Max +/-3%rh (0~80%RH), factory corrected Temperature accuracy: Error typ. +/-0.3%°c, Max +/-0.4%°c ( -10°c~85°c), factory corrected Measuring range: Temperature range 0~100%rh, maximum temperature range -40°c~125°c Operating voltage: 1.9~3.6v Low power consumption: Low 150μa at work, 60nA at standby Interface: I²C, maximum rate support

This blog tells me the idea and implementation of using Arduino to parse and forward raw NEMA 0813 data. Because Arduino is relatively simple, can not realize the serial data receive interrupt, so are written in the main loop inside. Do not know what flaws and loopholes in the code, you are welcome to criticize correct. GPS Software Requirements · Ardiuno Software · Monitor serial 1 to receive data. · Da

Arduino MQ135 Gas Sensor first, the wiring The MQ135 has 4 pins, VCC, GND, A0, D0, respectively, where VCC, GND, and A0 are required. The following diagram is a esp8266 wiring diagram. Due to the measurement of the gas value of PPM, it is related to the air temperature and humidity. So we've added a DHT22 here.

Analogwrite (pin, value) First follow the connection number Circuit 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
