I have had some spare time, so I decided to add front headlights to the toy car. I have used white LEDs:
I have connected LEDs to two GPIO ports (GPIO 21 and GPIO 20) and added the following net protocol commands to turn them on/off:
- FLL - forward left light on
- FRL - forward right light on
- FLL! - forward left light off
- FRL! - forward right light off
The Python code that receives commads over net is this:
elif text == 'FLL':
GPIO.output(PORT_FLL, 1)
elif text == 'FRL':
GPIO.output(PORT_FRL, 1)
elif text == 'FLL!':
GPIO.output(PORT_FLL, 0)
elif text == 'FRL!':
GPIO.output(PORT_FRL, 0)
Here is the movie in which I turn on/off lights:
