Control 2 Servo motors with a standard remote

This is a project to control two servo motors by using a standard remote control. It can form the bases for other projects and also the remote can control other items. As you will have full control of the program it is up to you.

This is a competed project running stand alone. The IC has been programmed to recognise the volume control and the channel change, these control the two servos. Advantage has also been taken of the toggle action of a remote so that if you keep a finger held down on the button of the remote the servo speeds up. Just pressing momentarily will step the servo a very small amount.
 

Step 1: Parts

The project is built in two parts, the first part is the development where communication is carried out with the IC over a serial link and the second part is a stand alone project as shown in the video.

* The IC obtained form ByVac There is also a kit available that has the serial lead (£9.50 for the kit)
* A USB to serial device if not purchased with a kit from above.
* Photodiode TSOP2236 or similar device Farnell part number 4913061 about £1 (see below)
* 3.3V regulator 100mA LDO type (only for finished project) Farnell part no 1296588 (see below)
* Remote control - From living room, only to be used in non-telly viewing time
* Breadboard - various sources
* Servo motors - various sources

The Photodiode and regulator can also be purchased from ByVac, Farnell may have a minimum order value. The photodiode is the type that is used in conjunction with remote controls, it has three wires and the one specified works at 36kHz.
