ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many innovative projects, so in this tutorial we

In this project, I'll show you how the Arduino connects to the alcohol detection sensor. Here, I have designed an Arduino Shield circuit board using the Easyeda online PCB designer. The Arduino Alcohol Analyzer detects the amount of alcohol in the breath, and then, by some calculations in the code, we can calculate the amount of alcohol in the breath or blood, an

analog signal Output [Mega] 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. The hardware required to complete this example Arduino Mega or Genuino mega board 12 x Red LEDs 12 x 220ω Resistors Jumper Bread Plate DuPont Line/C

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

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

For phprpc and Arduino, Google Before reading this demo, please install the SerialPort mentioned in another article. With another gem KIT: phprpc In this example, I established a server through phprpc and called some methods through rpc to control the USB serial port.In this demo, we must establish the server and client.T
