A simple program built with mbed and a Nokia N3310LCD screen. Using the USB serial and any terminal application, you can change the brightness to 4 led's. Instructions are on the screen to start. Enjoy and have fun! All feedback is welcome. Please email: d.b.searle@reading.ac.uk
Dependencies: N3310LCD mbed-rtos mbed Functions
