wiringPi是应用于树莓派平台的GPIO控制库函数,wiringPi中的函数类似于Arduino的wiringPi系统,wiringPi库包含了丰富的库函数,如GPIO库,I2C库, SPI库,UART库和软件PWM库。 二.wiringPi的版本信息查看 其实我们的树莓派系统里面已经自带了wiringPi库,打开命令终端,可以通过gpio命令来检查wiringPi的版本信息。 三.GPIO口...

This circuit works in two cases like turning on/off a load with a relay & a button. Once the button is pushed then the Arduino board will set pin-2 in HIGH condition, which means 5 volts on pin-2 of board. So this voltage is mainly utilized to make the transistor ON. So this tra...

IfmodeisINPUT, thepinis used asINPUT; for example, to read the state of a button. IfmodeisOUTPUT, thepinis used asOUTPUT; for example, to turn on/off an LED. Note that ifmodeis set toINPUT_PULLUPand the pullup resistor is around 20k ohms, that means if you use a pulldown resis...

TURBO: If you connect a button to turbo, you can use this button to “repeatedly press fire.” To do this hold the button you want to repeat (B1-B13) and while held press the TURBO button. The B1-B13 button held down will now act as if it is being repeatedly pressed. UP/DOWN/LE...
button.py Reads a digital input generated by a button connected to pin 2 and turns on LED 13 when the button is pressed. fade.py Fades up and down pin 5 using the PWM on the board. Conclusion wiring-x86is a very simple to use and yet powerful tool to control most of the I/O ...
If you are not using an Arduino, make sure your microcontroller can support "repeated start I2C requests"! Note the tab is how we will keep track of pins, in this wiring image, the tab is on the south side of the sensor, there's a red arrow pointing to it Connect GND to common ...
