RC Mini Car using the Arduino Nano 33 BLE #Bluetooth #Robots @bitbank

Larry on the bitbank software blog posts about building a remote-controlled car based on an Arduino Nano 33 BLE.

The Beetle-C has its own CPU to control the 7 RGB LEDs and 2 motors. This CPU exposes an I2C slave interface on the 8 pin connector (address 0x38). The car needs 2 power rails to operate. The 3.3v line powers the CPU and the 5v line charges the internal 80mAh LiPo battery. This little battery, in turn, powers the motors and LEDs. There’s no charge indicator on the Beetle-C, so I didn’t discover the power rail relationship until draining the internal battery by using the car with only the 3.3v line active.

For this reason, I chose to use a 5v DC-DC boost converter to provide 5v from my LiPo battery. This also makes it easier to power the Nano since the docs say that its VIN line needs at least 5V and connecting the 3.6-4.2v LiPo directly to the Vcc of the Nano might fry it. As far as power efficiency goes, this isn’t ideal, but I didn’t want to make major modifications to the Beetle-C nor the Nano to power them from the LiPo battery. The 3.3v Vcc of the Nano’s internal voltage regulator then powers the 3.3v line of the Beetle-C.

Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know –

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, 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.
