Circuits and electronics fundamentals

Module goal: calculate and design the basic circuits found on a development board.

Status alpha (in trial use) · about 195 minutes

You need: a calculator, a breadboard, a basic resistor set, an LED, a 100 µF capacitor, a multimeter, and a board (the part reading a knob through the ADC uses the TESAIoT Dev Kit)

Lesson	Topic	Time
elec.m01.l01	Voltage, current and resistance	65 minutes
elec.m01.l02	Voltage dividers and analogue sensors	65 minutes
elec.m01.l03	Basic components: resistors, capacitors, diodes and transistors	65 minutes

Module checkpoint

• can calculate the current-limiting resistor for one LED
• can explain that a knob on the board is a voltage divider, and how the value the ADC reads relates to the voltage
• can explain why every chip has its own decoupling capacitor, and when a MOSFET is needed to drive a load
