IR remote control (RC5)

[Vermes]

It is a simple system based on Attiny2313 – remote controlled switch. Remote control from tuner was used for control (red button does not cause any reactions on the tuner).

Elements used:

• double ARK connector x2
• Attiny2313 + base
• 7805
• 470uF/16V
• TSOP1736
• BC547
• 4,7k – transistor base
• 0,33k – TSOP supply
• relay with coil for 12V
• rectifying diode – protection of transistor
• 12V power supply

Code:

'wyłącznik RC5 by BM*
$crystal = 1000000*
$regfile "attiny2313.dat"*
Config Portb.0 = Output*
Portb.0 = 0*
Config Rc5 = Pind.6*
