The H8054 Mini PIR motion detection module is designed to provide basic motion detection to your project.
This is a very small light sensor. A photo resistor (also known as a photodector, or photocell) changes resistance depending on the amount of light it is exposed to.
The HC-SR501 is a passive infro-red (PIR) sensor which is used to detect motion based on the infrared heat in the surrounding area.
The HD2 tracked platform is a large, heavy duty tracked robot with the power to pull a truck and climb stairs. A wealth of internal space allows for batteries, controls and an optional computer. Customized version of item TP-200-001.
2WD self balancing robot! This kit is a perfect plataform for learning Arduino, PID control, serial communications(Serial, I2C, SPI), PWM signals, IMU filtering, etc.
