The TinkerKit Arm is a fully operational Robotic Arm, controlled via Arduino. It can be assembled in a variety of ways for various tasks, such as moving objects. You can also attach a camera or solar panel. There are many ways Arm can extend the range of your devices.

The TPBot has the appearance of a toy and works as one, since it can be used very easily to follow lines, avoid obstacles or let it work alone (in entertainment mode). However, once the Micro: Bit is inserted, it becomes a super-complete and fully programmable smart car. It's great for working in a classroom, you can expand it with extra electronic modules and add Lego pieces.

This UV Sensor is capable of detecting UV solar radiation using a simple UVM-30A chip. It can be easily configured for projects with Arduino to monitor UV Index, analyze UV-A lamps or DIY projects as plant growth analysis.

The Pololu USB to serial adapter is great for connecting microcontroller designs to a personal computer. The adapter uses 3.3 V signal levels so you can connect it directly to any microcontroller running at up to 5 V without the hassle of an RS-232 to TTL level converter.

Wio Link - IoT Controller

The Micro:Bit Wonder Building Kit focuses on brick expansions with 20 designs available, and youcan build more designs. Equipped with several electronic sensors, such as the Line-Following Sensor, the Sonar:Bit and the Water Level Sensor, which enrich projects with more challenges and fun.
