I want to create a circuit which will wirelessly drive a relay. I only have a little experience with Arduino. I know what peripherals I need, but I don't know what micro-controller to use. I made a list and I need to know if the components will work all together with the microchip PIC18F26K80 microcontroller, or if you have any other (cheap) suggestion.

  • a relay like that
  • the uln2003 to drive the relay from the microcontroller
  • a Wireless RF Transceiver(10 pin) 915mhz
  • a programmer like that
  • ethernet magjack (to be able to send and receive tcp/udp packets)

  • \$\begingroup\$ Why specifically a 10 pin wireless transceiver - that seems OCD? \$\endgroup\$ – Andy aka Jul 25 '14 at 11:12
  • \$\begingroup\$ Because every wireless transceiver at 915mhz that I found has 10 pins and i dont know if have to use all of them \$\endgroup\$ – teo6389 Jul 25 '14 at 11:25
  • \$\begingroup\$ Why do you need an ethernet port if you're running this wirelessly? Might be easier if you're starting out to go for the arduino and shield route \$\endgroup\$ – ArthurGuy Jul 25 '14 at 11:59

Well you can use a much cheaper PIC, like the 16F88. RF transceivers are not "that" easy to use, you could try the HC-05 bluetooth modules : they're simple "transparent" bridge, and you communicate with them through a UART (16F88 has 1 UART, and it's real easy to set up) and Arduino has one too.

You should consider buying a microchip PicKit3 instead of a cheap eBay icsp programmer. PicKit's firmware is regularly updated and programs virtually any PIC.
