Resistance
- The resistor code
- Using a multi-meter to measure resistance
- What is your Ω
Voltage
- how to use a breadboard
- Measure voltage from power to 5V
- Put two resistors in series and measure voltage in middle
- Put resisotors and LED in series
Putting it all together
Avoiding delay
JavaScript doesn’t allow delay operators, though you can use
setTimeout to achieve the result.
Let’s try out
blinking
without a delay to see some clever things you can do with a clock.
