Two missions for today: to explore sound sensor and PIR sensor

IMG_1011

we’re going to test this sound sensor to detect the beat of a music and make a LED blinking the beat 🙂

the code

serial monitor

IMG_1014 IMG_1015

setting up the sensitivity of the sensor

IMG_1016

and after that, it works 🙂 *find the link of the videos on the bottom of the page

IMG_1018

PIR sensor, took some time to warm it up

IMG_1020

so far, after testing 2 PIR sensors, ultrasonic sensor is more reliable 🙂

Our regular private class 🙂

Today Tyo finished 2 projects: temperature and humidity sensor and LDR sensor

Temperature and humidity sensor

The result

Two projects going very smoothly today, and Tyo is busy sorting the books for his mobile library after the class 🙂

Next week we’re going to explore more projects 🙂

Our quest today is to finish the timer 🙂

IMG_9740

IMG_9741

We not got hour:minute:second format

IMG_9743

We added potentiometer to select the number, but first we test it with LED

IMG_9747

and then show the value on the LCD

IMG_9749

Next week we will explore temperature and humidity sensor 😉

ProCodeCG – Kids Private Class – Basic Electronics – 11 April 2019

Standard

This is our plan for today: creating a timer with 2 or 3 buttons 🙂

IMG_9372

Tyo is so ready 😉

IMG_9373

It requires lots of coding modifications

IMG_9375

IMG_9376

The wiring is ready but not yet the coding

IMG_9377

We added more details and features

IMG_9379

We still have to fix the information printed to the display

IMG_9380

and the third button is still not working

IMG_9383

We should add clear display in the loop so it wouldn’t get overlapped characters like this

IMG_9385

the up and down button is working well

IMG_9388

IMG_9390

We will deal with the third button on the next class 😉

Tyo couldn’t wait to continue his timer project 🙂

IMG_8822

but we have to do it step-by-step: installing and testing the components separately and make sure they are working properly before assembling them into the final project.

The first one to test is the button for setting up the timer

IMG_8824

ok buttons for setting up variables are working

IMG_8825

next is designing the view 🙂 Tyo wants to have scrolling text so we test the scrolling function

IMG_8828

this one is also working

IMG_8830

the next is to set up multifunctional button for starting and stopping the timer

IMG_8832

Tyo had to do lots of modifications to the code, and his skill and experience in Java programming comes in handy 😉

IMG_8833

Next week we’re going to put all together 🙂

Tyo has chosen a project for today: a timer with buttons and LCD 😉

8DD0B730-B8F8-4936-B437-B992FC9374CD IMG_8361

It requires lot so of modification from the latest work

IMG_8362

The schematic

IMG_8363

Testing and debugging

IMG_8365 IMG_8366

IMG_8367

All is working well, the button will start and stop the timer and the buzzer. Next Tyo will add another button to set up the timer and make it count down 😉

Today Tyo learns how to use an LCD I2C 🙂

IMG_7949

IMG_7946

IMG_7945

The “Hello World” 🙂

IMG_7947

And then we’re adding an ultrasonic sensor and will send the readings to the LCD

IMG_7951

Tyo had to combine the ultrasonic sensor code with the LCD I2C code

IMG_7952

Debugging the cables

IMG_7953

The target today is done 😉 For the next project Tyo wants to make a timer with LCD I2C and a button to start and stop it 🙂
