These can be set by means of the attr command, displayed with the displayattr command, and deleted by the deleteattr command. There are global attributes that are used by all devices and local attributes that apply to individual device classes only. See the documentation of the attr command for examples. Be careful not to overwrite additional global attributes previously defined by yourself or a device.

Three buttons are used to command the circuit. The unit provides 10 way speed control from 0 to 9. The current speed is displayed in a seven segment display. In the Video below you can check out the project in action. The main parts of the circuit is labeled below.

The seven segment display used to show the current speed level. The TSOP sensor is used to pick up commands from remote control. The Yellow LED indicates the power status of the load. Tested on v 50Hz AC line. IN — Power supply from a transformer is applied here. Construction of Remote Controlled Fan Regulator.

You can make the circuit as per the schematic on any general purpose PCB. You may also have the PCBs made from any fabrication house too. To further easy the job and save your money we have already made the PCBs from a good fabrication house and they are available for purchase at very low cost.

Start assembly process by first soldering the jumper1. Then you can mount the resistors. After that solder the diodes, remember to properly orient the diodes. Then solder the IC U4 and U2, this time too take care of the orientation.

Finally Connect the Transformer and apply power. The display should change accordingly.

Embedded Engineering : IR(infrared) Remote Control Relay Board with PIC 12F Microcontroller

This ensures that the circuit is running properly. Its time to connect a real AC load.

As shown in the above wiring diagram. Replace the fan with bulb because its easier to test. Never Touch any part of the circuit when AC load is connected.

It can give you a fatal shock!!!Can I use the GPIO as a pulse-width modulation output? If so, how would I go about doing it and how many concurrent, distinct PWM outputs can I have?

Can I use the GPIO for pulse width modulation (PWM)? up vote 90 down vote favorite. Software PWM. The Raspberry Pi is not suitable for any serious software PWM as Linux is not a real. Accessing The Hardware PWM Peripheral on the Raspberry Pi in C++ In this Blog entry I will demonstrate how to access the single hardware pulse width modulation (PWM) channel available on the Raspberry Pi.

PWM on raspberry pi. With only one hardware PWM pin on Raspberry Pi it can be quite a problem with Arduino users like ashio-midori.com are various hardware solutions available to overcome this ashio-midori.com ADC(analog to digital converters) IC are available which can be interfaced via I2C ashio-midori.com this post I will be using WiringPi library which can bit-bang .

A long form guide about installing Linux on the Dell Venue 8 Pro () Bay Trail tablet with Arch Linux and Friends. raspberry-gpio-python A Python module to control the GPIO on a Raspberry Pi Brought to you by: croston.
