Recently, we saw how to connect the Lego Boost robotics set to the Raspberry Pi, and how to communicate with it in Python. This time we look at three example projects, where we explore the finer points of control that are normally hidden from you by the standard Lego software.

The Lego Boost system communicates with a Move Hub that receives instructions, in real-time, over Bluetooth – it does not store its own set of instructions. So your model has to be in Bluetooth range all the time. This month we have three models to build, explore, and program. First, a simple but amusing use of the tilt sensor, then a machine to explore the performance of the colour sensor, and finally a colour sequence memory game. All parts for these projects can be built using the bricks that are included in the Lego Boost 17101 set.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
