The project can be used effectively to detect fast moving objects using sensors made from LED array. One of the slave microcontrollers (Slave A) is the PIC16F876A which autonomously scans the bottom ...

LumiBright UV boards, leveraging chip-on-board LED technology with metallic-core printed-circuit-board (PCB) substrates, feature a large emitting area using a closely packed array of UV LED chips to ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...
