After the download is complete, you can find the following version file: Arduino-1.8.2-windows.exe This is the latest version and will be updated as time progresses. When you insert the

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.

The principle is not complex, because arduino is already a database with a bunch of avr +, just find a tool that can compile and translate hex and download it to the board. However, we still encounter many problems. First, make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x4217b3) appears during eclipse + avr plugin compilation) Make cannot contain spaces like Program Files in the path.

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\

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
