UNO Project 2WD Smart Robot Car Chassis Kits SR04 Ultrasonic Avoidance Sensor Line Tracking Speed E
[4000141403390] UNO Project 2WD Smart Robot Car Chassis Kits SR04 Ultrasonic Avoidance Sensor Line Tracking Speed Encoder Motor Module for Kids 【Easy to Install】The entire mechanical structure is simple. Nice project for kids that want to learn how to use for arduino 【With 4 Battery Compartments But Without Battery】It is convenient for the whole power system, and provide with a switch, easy to start-stop. So that to make the entire system is highly integrated 【With L298N Driver Module】Dual-channel H-bridge driver working mode creates higher working efficiency. L298N as main chip,Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors 【With SR04 Ultrasonic Sensor Distance Module】using IO trigger for at least 10us high level signal. It can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning 【Note:】The UNO is belong to CH340 version, so you have to download the CH340 driver to use it. Please kindly know it
