In this lesson, we will create a simple build using a pushbutton and 4 LEDs. I’ve got an idea for a project that would simulate a railroad crossing with a flashing signal, a buzzer for the siren, and a crossbar that lowers and raises with the press of a button.…

So far we’ve been writing digital signals to control an LED. Today we will use analogWrite to do it in a similar way, but now we will use Pulse Width Modulation (PWM) over an analog pin. I highly recommend watching Paul McWhorter’s video on PWM for a detailed explanation of…

In our last lesson, we set up three LEDs and wrote code to blink them on and off, using variables to represent the different digital pins. We basically copied and pasted the code in order to blink an LED the number of times we wanted. Today, we are going to…

In my last post we recreated the simple Blink program from Arduino using the built-in LED on the board. The program simply turned the LED on for one second and then off for a second. Today we will add three LEDs to the breadboard, along with resistors to keep the…

Hi guys, I’m back after a loooonnng break from the blog. I’m sitting here on self-quarantine during the coronavirus pandemic of 2020 and thought, dang, I’d like to get the Maker Daddy blog up and running again. So, here I am. It’s been so long since I’ve played with the…
