Week # 6- Journal

7- electronic components for making the model with Arduino board

1- make the circuit in tinkercad (arduino uno,breadboard,servo motor,2 red leds ,ultrasonic sensor,5v adapter,2 resistors)

2-write code by tinkercad blocks and arduino ide

block code description : my flow is when ultrasonic sensor sense any motion as (input) leds will turn on and servo will start moving as (outputs)

so I started with put if conditioner block and in it i put rotation servo block to put pin wich will connect with arduino and to limit servo angle after that i put delay block to stop time for 1 second ,then rotate servo back

i also put leds block to write pins number and her situation(high , low)

and finally i put on else block the opposite of all above

3- test simulation of circuit in tinkercad

4-make the circuit real

5- make the model by paper , scissors ,hot glue and string for connect servo with tail and but the circuit in body

1- make an experiment to run circuit

i connected servo motor , 2 red led s,2 resistors and ultrasonic sensor in breadboard with arduino and adapter by jumper and common pins in breadboard .

• i put negative pin of adapter in negative common pins in breadboard and positive pin in positive common pins in breadboard too and make common ground with arduino

• put (+) pins of 2 leds in digital pins of arduino and (-) pins of leds with 2 resistors and the another pins of resistors in common (-) breadboard

• signal pin of servo in pwm pin in arduino ,gnd pin in common ground in breadboard and power pin in (+) pin of adapter

• echo , trig pin of ultrasonic in digital pins in arduino ,gnd pin in common gnd in breadboard and vcc pin in 5v pin in arduino
  

2-i make body of scorpion by colored paper , scissors and hot glue and make spaces in tail to be enable to collect it with servo motor

3- i powered this circuit by Arduino and 5v adapter

1- I had a little confusion about how to operate the servo from the adapter and the sensor from the Arduino, and both of them came up with one code via the Arduino, but Youssef ali did this circuit with me in Saturday's project with the idea of ​​a common ground in breadboard, so I was able to understand the solution to the problem and how to distribute a current from different power sources and keep the whole circuit connected together

2-I had a problem that I wanted to control the speed of rotation of the servo axis and its exact angles, and Mahmoud ezzat helped me to understand through the code how to control the speed of the servo that I supply more dilay when I specify the angle of rotation

3-I had a problem with controlling the tail by attaching the thread to the servo, and I used to stick the thread at the upper end of the tail, but I discovered for easier control and assembling the whole tail so that I fixed the thread at the lower end of the tail

1. i have learned how can i write code with tinkercad blocks and send it to software arduino

2. i have learned how to use tinkercad software to make circuits and simulation them

3. i learned how can i Combine two different current sources in one circuit

4. i learned how can i control servo with sensor and how con i control angel rotation of servo

5. how to use breadboard to get connection easier

6. use Arduino to control circuit of components

7. and how can i use electrical curcuit with arduino ,input and outputs to build a nice project
