This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller. Overview...

Description The Parallax ColorPAL combines an RGB LED, a light sensor, and a microcontroller to make a color sensor that can also be used as an ambient light detector and a color generator. Readings are reported via a 1-wire asynchronous...

Overview This breakout board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, +5V VCC, and an analog voltage output—that are broken out with a 0.1" spacing, making the board...

Motor Connections These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our mini plastic gearmotors. They also work with our 35:1 and 115:1 15.5D...

The Tamiya slick tire set contains four wheels with arched tires, each with a diameter of 31 mm (1.2") and a width of 10 mm (0.4"). These wheels are compatible with Tamiya gearbox kits with 3mm-hex shafts The Tamiya 70192 slick tire set...

The Tamiya 70111 sports tire set contains two attractive racing-style wheels, each 56 mm in diameter and 25 mm wide. These wheels are compatible with all Tamiya gearbox kits. The Tamiya 70111 sports tire set includes the following: Two...

The two extremely springy tires in the Tamiya 70096 off-road tires set are about 50 mm in diameter and 30 mm wide. Use these if you want your robot to have a soft, air-cushioned ride across rough terrain. (Compatible with the Tamiya...

The Tamiya 70194 spike tire set includes two wheels designed for bumpy and rough surfaces, each with a diameter of 65 mm (2.56") and a width of 26 mm (1.02"). These wheels are compatible with all Tamiya gearbox kits. The Tamiya 70194...

This plastic Futaba servo wheel is made to match Futaba servo splines, such as those on theSpringRC SM-S4303R and Power HD AR-3606HB continuous rotation servos. The wheel is molded from ABS and measures just under 2-5/8" across by 0.3"...

This plastic Futaba servo wheel is made to match Futaba servo splines, such as those on theSpringRC SM-S4303R and Power HD AR-3606HB continuous rotation servos. The wheel is molded from ABS and measures just under 2-5/8" across by 0.3"...

The Solarbotics SW wheel is compatible with standard Futaba servo hubs such as those on theSpringRC SM-S4303R and Power HD AR-3606HB continuous rotation servos. The plastic wheel is molded from ABS and has a molded-on thermoplastic...

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be...
