At Clover Park Technical College, in the Mechatronics program, I took a course in DC circuits and Computer programming with C++. Essentially I got to build and troubleshoot DC circuits on breadboards, some using an Arduino micro-controller which was programmed using C++. Below are some videos of different projects I've worked on.
Using random values, leds and a buzzer.
Using user input, relay, button, and some leds.
This is me using an led, potentiometer, transistor, relay, photoresistor, and an Arduino uno.
Me using an integrated circuit.
Interrupts, button, relay, etc.
