LEARNING:
This Tuesday the teacher showed us the different types of telephone signal sensors and plates that we are going to use for the rest of the year.
He explained the parts of the board and how it works, along with the features they have.
I learned that cell phones carry 3.3 v and others carry 1.5v.
Homework:
- Electrical characteristics of arduino.
- Scratch characteristics for arduino.
solution :
Characteristics of arduino:
- Microcontroller: ATmega328
- Operating voltage: 5V
- Input voltage (recommended): 7-12V
- Input voltage (limits): 6-20V
- Digital I/O pins: 14 (of which 6 provide PWM output)
- Analog input pins: 6
- DC current per I/O pin: 40 mA
- DC current for 3.3V Pin: 50 mA
- Flash Memory: 32 KB of which 0.5 KB used by the bootloader
- SRAM: 2 KB (ATmega328)
- EEPROM: 1 KB (ATmega328)
- Clock speed: 16 MHz.
Scratch Characteristics for Arduino:
Entorno del S4A
The S4A interface is very similar to Scratch 1.4 in that it is a version of it.
In the scenario you will see a table of pins inputs and outputs of arduino board and a drawing of it, if this is not connected will appear a message "looking for board" which will disappear when the S4A recognizes it.
scratch for arduino has several specific blocks to connect to arduino, they are in the "motion" section and are the ones that allow sending instructions to the arduino board micro-controller.
In the same way, editing objects brings with it buttons to create, draw and import arduino objects.
