Trying to figure out if it's suitable for breadboard use or too thick/thin. Any way to estimate gaugeCMOS decade counter CD4026BECommunity Q&AIm having so much fun with this kit! I ran into my first noob problem with the CMOS decade counter CD4026BE. I wired up this circuit from make electronics and I think I had a issueHow many components can I safely plug into one breadboard power rail row?Community Q&AGetting to more complex circuits now with several LEDs, a 555 timer, and a potentiometer all sharing the same red/blue power rails on one breadboard. Is there a limit to how much IDC motor driver — do I really need a transistor, can I connect the motor straight to Arduino pin?Community Q&AWant to spin a small hobby motor from an Arduino digital pin directly with digitalWrite HIGH. Seems like it should just work like an LED does. Do I actually need a transistor or drMaking an LED brighter without burning it out — is there a safe max current?Community Q&ACurrently running my LEDs pretty dim with a 1K resistor because I'm nervous about burning them out.

The book keeps talking about digital pins vs analog pins and I get that digital is on/off, but thMultimeter reads 0V everywhere even though circuit is poweredCommunity Q&AMy multimeter is showing 0 volts no matter where I probe, but I can see the LED is lit so I know current is flowing. Battery snap connector is new. Am I doing something wrong with How does a 555 timer astable circuit actually decide the blink rate?Community Q&AWorking through the 555 timer chapter and I got the LED blinking circuit working which is awesome, but I don't really understand WHY changing the resistor values changes the blink LED not lighting up at all — checked polarity twiceCommunity Q&ABuilt a simple LED + resistor circuit on the breadboard powered by a 9V battery, LED is dead, no light no matter what I try.
