Bob Alexander built Blueprintf, a handheld serial monitor with data displayed on a cell phone.
I built a handheld serial monitor to use with my microcontroller-based projects, allowing me to debug them or send them commands from my cell phone or tablet. I can connect it to my project’s UART with two or three wires, then connect via Bluetooth to my cell phone, set the baud rate or auto-detect the rate, and then have one or two-way communication between the phone and the microcontroller. You can see my write-up at http://www.galacticstudios.org/blueprintf/. I’ve also posted the code, schematic, and PCB layout files.

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.
