Are you aware what a “Wordclock” is? A Wordclock is a clock that shows the time by lighting up sure letters, contained in a matrix, in an effort to write the phrases akin to the present time. On this challenge we’ll see another Wordclock utilizing 3D printed letters, which can transfer by a magnetic system.
Every letter has a magnet on the again, which will likely be attracted or repelled by the magnetic area generated by a coil constructed on PCB. These coils are managed, by a number of DRV8912 multi-channel H bridges, with an ESP8266. The latter will enable, by WiFi communication, to have the ability to change the time utilizing a smartphone.
