Bluetooth Tracking / Obstacle Avoidance Car
Overview
The UNO bluetooth intelligent car is a single-chip learning and application development system based on the arduino micro-controller ATMEGA-328.
It has 4in1 functions such as tracking, obstacle avoidance, infrared remote control and remote bluetooth.
The kit contains a number of interesting programs that can extend the external circuit modules to raise the fun during developing mcu systems. The pre-drilled holes on the chassis frame area are a standard machine drilled format. All component modules may not align with the holes due to manufacturer variations. Custom holes will have to be drilled by the user as required.

Great buy!

My husband loves these. The socks are warm and thick and extremely comfortable. They support the foot and he works outside all day and has had them for a little over a month. They stay in place and don’t move move around while he’s outside moving around.
