The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

An Arduino Uno and the relays for the laser and fans sit on the MicroSlice’s bottom platform, and two EasyDriver motor controllers sit above them on the next layer.

Light fidelity (Li-Fi) is a widely adopted form of wireless communication that uses optical energy to verify device ...

The MicroSlice laser cutter and engraver offers a working area of 50 x 50mm and is capable of cutting through paper and engraves wood & plastic using a 100mw Red Laser Diode, like you’d find ...

The Arduino illuminates (blasts) the target using an inexpensive laser diode mounted on a servo motor. Interesting applications of applied math include computing distance based on sonic travel time, ...

The laser diode outputs can tolerate voltages up to 10 V to make it possible to use laser diodes with a high forward voltage. In addition, power control for the laser diodes is performed by ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject # ...
