We’ve all been there. A circuit – either of your own, DIY design or some slightly pricey commercial product – isn’t working as intended. And when you dive in to troubleshoot the circuit you encounter something novel to say the least. Here’s a fun quick story by Brian Zabel for EDN on exactly that, involving a teenager’s faulty phone, or is it the charger, or is it the wire? Read more to find out!
On a school night one spring I was at home, winding down for the evening, when I got a troubleshooting request from my frantic stepdaughter. It seemed that her cell phone was almost dead and would not charge at all. Those with young teens in their lives will appreciate that her social life would purportedly suffer irreparable damage the next day unless I provided a fast and immediate solution. To calm the “client” without making any promises, I started with, “Well, let me take a look.” This was followed by more than one “Hmmm” to assure all that much thinking (not to be confused with inaction!) was taking place.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
