It’s been about a year since my last tutorial. Over the last year I learned that teaching in the real world will take away time from teaching in the virtual world. Many people have contacted me asking about a tutorial for the 555 timer in Monostable mode. The great thing about this mode is that you […]
If you’ve been following along with the 555 timer series, this video describes how to derive the formula that describes the timing of the circuit. Starting with just 2 components, we’ll work our way to an answer.
Continuing with a focus on the 555 timer, this video tutorial looks at how to vary the pulse width of a 555 timer’s output. It’s all possible with just a a hand full components. By varying the duty cycle one may vary the blink rate on an LED or the voltage being fed to a servo. Enjoy! […]
For the past several weeks we’ve looked at blinky LEDs, 555 timers, and resistors. This week it’s time to put it all together into an application. A YouTube subscriber suggested the project as follows: How would you go about having an led blink twice, then a different one blink twice, then back to the original […]
In this weeks video we’ll take a look at how to use an LED. There are tons of LED related projects out there but what if you want to integrate LEDs in your own project? When your finished with this video you’ll be able to pick the appropriate type of LED for your project and […]
