Board layout goes a lot faster with help from Mho and Hans – Circuit Playground
Board layout goes a lot faster with help from Mho and Hans 🙂
Mho has a laid back, passive personality. He likes to do as little work as possible, and prefers to simply let the world happen around him. Mho is kind of a hippy, and is very quiet and gentle. He is best friends with Ruby, the red LED, who shares his idealism, though he’s often reluctant to go off with her on her adventures because he thinks they will probably end up in trouble. Mho has sort of a nasally, hippie voice (California accent, but not a surfer). His catch phrase is “no worries, man. it’s all easy.”
Resistors are passive electrical devices that resist the flow of an electrical current. The voltage across and the current through a resistor are related by Ohm’s law. Unlike capacitors and inductors, the resistance of a resistor does not change with its frequency. The amount a resistor constricts the flow of a current is its resistance. ‘Thru-hole’ resistors are labeled by their resistance using a color band scheme.
Hans is the ‘old man’ of the group. He tends to be nervous and is often indecisive. Hans frequently changes his mind, and is a little fidgety (he oscillates) when he’s not moving around. He is very meticulous and precise in other ways; Hans does not like to compromise, preferring to be in a steady state until a dramatic change is called for. Hans speaks with the voice of a kindly old man with a Swiss-German accent, though his voice can become more nasally when he’s upset or feels strongly about something. His catchphrase is “maybe so, but perhaps not.”
About the 555:
The 555 timer IC was designed by Hans Camenzind in 1971. It consists of two threshold triggers, an RS flip-flop, and an output buffer. The 555 provides an easy, reliable way to create rectangular waveforms of adjustable pulse width and frequency by using different external component values.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
