ARDUINO REMOTE SENSING AND CONTROL USING 433 MHz MODULES
Components Required for these Projects
The components required for these experiments are not expensive and you may already have some of them -
The 433 MHz Tx/Rx modules are very good value for money and represent an excellent starting point for people wishing to explore the realms of remote control and sensing.

Components for the Experiments
The prices given are only a guide price and higher and lower prices can frequently be found.
Many of the cheaper suppliers are located in China and therefore delivery times may be considerable (up to several weeks) and therefore a supplier based in your own country is often preferable if you want your components quickly.
The fact that a supplier is named in this list is not indicative of an endorsement of its reliability or the up to date cost of the component.
Many of the components and Arduino boards are supplied with the headers not soldered in place. This does give you the flexibility in whether male or female, straight or angled headers are fitted. Note that if a shield needs headers soldering on they must be at 90 degrees to the board and chosen to allow the shield to be mounted on the Arduino Uno.
Use a fine tipped soldering iron and a good quality multicore solder. Check for accidental solder bridges with a multimeter or continuity tester before using the component especially when soldering headers to a shield or the Arduino Uno. It is also worth checking the header connections on new components when you receive them, as sometimes the soldering is poor. It is easier to check this first before you completely rewrite a program you have written because it is not working!
