Week 7 Servo Motor

 How Servo motors work.


From https://en.wikipedia.org/wiki/Servo_control#/media/File:Servomotor_Timing_Diagram.svg

Now for a cycle of 50 Hz this means.....

Each cycle lasts 1/50 sec = 0.2 sec = 20 ms 

For -90 degree position

1ms /  20ms  =  5%

1.5ms /  20ms  = 7.5% duty cycle for 0 position

For 90 degree position

2ms / 20ms = 10% duty cycle

How a servo motor works




So...

 percent_duty_cycle = 0.0278 * degree + 7.5

Week 1 Setup. Using Thonny

 Information Links Raspberry Pi Foundation doco link  Pico2 Datasheet Raspberry Pi Pico Workshop for Beginners micopython quick reference  (for pico2) picozero guide My Github location  W3Schools Python Tutorial micropython standard libraries parts catalog (use to look up data sheets) Date Change There is no Lesson on the 6th November.  Instead we will be holding a double lesson with a 30 min lunch break from 10am-2pm on Oct 30. Maximum Load on IO pins  Current/voltage limits This section is important to not damage your Pi Short version the IO pins can pass 12mA of current.  In OUT mode that is supplied at 3.3V V = IR V/I = R 3.3/0.012 = R R = 275 Ohms What this means is the minimum resistance on a circuit using the IO pins is 275 Ohms. To be safe add 50 Ohms to that. The maximum voltage supplied to an  IN IO pin should be 3.3 V Other limits... 3.3V output has a maximum current of 300 milliamps VBUS (Which only works with USB input) supplies USB ...

Week 2 Resistors, Using the Solderless Breadboard, Turning an LED on and off using the Pico

 Resistors Reading Resistors Using the Breadboard Power to the Breadboard How the jumper pins work for 3.3V and 5V  What pins are connected on the board. How to use the connectors LEDOnOff Program How IO pins work. How Breadboard pins work Meaning of extra names on pins (Especially SPI pins) Safety with Pi Set all pins to input at close of program Unplug Pi to set up circuit If doing something you are unsure of test with LEDs or Multimeter. Have no physical connections to expensive laptops etc. (More on running the pico without a laptop connection later) Try with 500 ohm resistor first. Run LED program on pico. Explaining the program Commenting with # The importance of indents in python try, exception, finally Homework Make your LED flash an SOS in Morse Code S is 3 dits.  O is 3 dahs The Dot (Dit):  The shortest element, representing 1 unit of time. The Dash (Dah):  A longer element, equal to 3 dots in duration. Intra-character Gap:  The short silence betw...

Week 3 Introducing Python Coding, Pulse Width Modulation

 Python Coding Program set out imports constants global variables functions main block Program Exercises Comments Constants ( Why we use them,   Where do they go) Variables Data types Operations Micropython is different to standard python.  They have to pack a lot into a little microcontroller.  So if something works on your local machine interpreter but not on the pico have a look in the differences doco for work arounds Work through the exercises in basics/variables.py Pulse Width Modulation (PWM) Watch Core Electronics video on PWM Set up led_pwm.py on breadboard and run.
