Joystick with Cherry MX keys using an LED
« on: 04:31, 26 July 21 »
Hi,
I would like to build a Joystick using Cherry MX keys.  The keys have a provision to place an LED under the keycap.  Is there are way to turn on the LED when a key is pressed?  Without using any additional power supply, can I route the switch to the LED? IE: UP key is active when PIN 1 is connected to PIN 8, use this connection to power the LED?
Thanks

Won't work without additional PSU since the CPC got no 5V on the joystick port ...
