ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 4 Nov 2017


Hello Saturday πŸ™‚ Always looking forward to see kids coding in our class πŸ™‚

Morning prep πŸ™‚



Ozan continued working on adding buzzer to his ultrasonic counter

Ozan had to check simple buzzer code to be added to the new code

Took a lot of effort because the same problem occur: the ultrasonic counter doesn’t work with buzzer added


Nafis was back πŸ˜€ He’s doing the same project as Ozan and Reza


And Nafis agree to start it all over again and add the components one by one, using ESPectro πŸ™‚


Reza helped to make Nafis’ work


And after the ESPectro shut down for several times due to wrong polarity, it finally worked πŸ˜€ but not yet with buzzer and LED πŸ™‚


The most mysterious thing is that Reza’s wouldn’t work


It took Reza hours to debug

He changes the components to find the problem


Still didn’t work, so we decide to take Ozan’s to be tested on Reza’s code


And yes it worked πŸ˜€ So we combined Reza’s code with Ozan’s board and it worked well πŸ˜€


We’re still curious to find out why Reza’s didn’t work (but at least he has a code that worked well). Reza is a very persistence kid. Won’t stop until it’s done πŸ™‚ Now to buzzer will beep when the count reaches 20 πŸ™‚


Next week we will add LED to it πŸ™‚
