Sensors & Indicators
The Blinkin LED Driver (REV-11-1105) is designed to make it straight forward to add controllable LEDs to a robot, cart, or any other project which would benefit from some extra lumens without needing any specialized programming. The Blinkin is a compact, all-in-one solution which can control LEDs in a stand-alone mode with just a 12V power source or in a dynamic mode, changing patterns by supplying a standard servo-style PWM signal.
This 12V RGB LED Strip (REV-11-1197) is compatible with the REV Blinkin LED Driver (REV-11-1105). Each LED on the strip is wired in parallel and actually contains three embedded LEDs; a red, green, and blue LED. Each color can be controlled separately to create any color that you desire. Because these LEDs are wired in parallel, the entire strip will be the same color.
The REV Robotics Color Sensor (REV-11-1557) V3 is a combined color and proximity sensor. From a single sensor you can measure colors and rough distances to various targets. Version 3 introduces a new sensor chip from Broadcom due to the end-of-life of the V1/V2 color sensor chip.
The REV Robotics 2m Distance Sensor (REV-31-1505) uses the ST Microelectronics VL53L0X Time-of-Flight (ToF) laser-ranging module to measure distances up to 2m with millimeter resolution. Unlike other ranging sensors that rely on the intensity of reflected light, this sensor can measure how long it takes for the light to bounce back, the “time of flight.” This results in much more accurate measurements that are independent of the target’s reflectance.
The REV Robotics Magnetic Limit Switch is a three-sided active-low digital hall effect switch with three internal hall effect elements located on the top and sides of the sensor. The three elements are connected in parallel so that any one of them will trigger the sensor.
Hall effect sensors detect the presence of magnetic fields. The REV Magnetic Limit Switch is an omnipolar momentary switch meaning it will trigger when there is sufficient field strength of either magnetic pole (north or south) detected.
