Getting to serious Stuff yaaaay

ok so last class meeting we did a lot of electronic stuff and played with switches, LEDs, relays and boards
first we made a simple board with switches and LEDs just to learn how to connect a LED to a switch and here is the result of my attempt

after mastering the first assignment we used a relay and a switch to light one LED and then the other when when the button on the switch was pushed and there is the result

then the goal was to learn how to use relays and a switch to make two LEDs flash on and off periodically. I accomplished the mission successfully as you can see in the following picture:

and finally after doing one more setup with the board and the relay to see what happens when the relay oscillate very fast (if we pushed the switch button it made the relay to oscillate real fast which produced a buzzing sound) we finally got to build a robot.
we built the robot however from a guide just to get familiar with the concept but it was exciting to know that we are getting closer to the serious materials.
