Hi! Nice work on that.
Just a thought since you put up the LED display that you might have some programming fun too – you could make the display scroll your name or something over by turning the individual LEDs on and off. Since you only have 4×5 lines you’ll need a small font, I found one that you could mimic: font.gif…
The trick is to use time division to blink the individual LED’s for just a fraction of the time you need. If they blink fast enough our eyes don’t notice them blinking and they look steady.
Have fun!
Holy cow Tshepiso, that’s a lot of hello worlds!
Now that you’ve made all of them, which one would you recommend a new user make first? Which one did you have the most difficulty with?
I would recommend that a new user to make the hello-speaker first as it has less components.
the tricky one was the LED circuit, as i swap around the cathode and the anode and after programming the circuit, one LED was not working and i had to make another circuit.
