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
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 Volts (Usually 5.5) and a max current of 2amps
Any greater outputs need a driver.
Setting up Pico
Install the latest version of Thonny (4.1.7 is the latest version and is required as there is a bug in previous versions that prevents you downloading packages)
Using Git
Follow guide
Homework
Write any Hello World type program on the Pico yourself. (Save to your computer not the pico)
