It's build day!
That's the best day of the week.
But first: Have you ordered the components yet?
If not, go back to lesson 6 to see how to get your hands on the right components.
In this lesson, I'll show you how to build the blinking light circuit.
Let's start with the complete circuit diagram:
(The numbers next to each pin in the diagram represent the pin number of the Hex Schmitt Trigger Inverter.)
Component List:
BATT1: 9V Battery
U1: Hex Schmitt Trigger Inverter (74C14 or CD40106)
C1: Polarized Capacitor (100μF)
R1: Resistor (10 kΩ)
R2: Resistor (10 kΩ)
LED1: Light-Emitting Diode (low power)
Breadboard Connections:
If you just want to know how I connected it on my breadboard, here's how:
Step-by-Step Instructions:
I've created step-by-step instructions that will explain each step I did to arrive at the connections shown above.
And you can use the comment section to ask questions if you're struggling to get it working.

Summary:
In lesson 6, I showed you how to get the components. In this lesson, I showed you how to build the circuit. I can't build it for you - so now it's up to you to take action. And if you want to learn electronics, there's no way around it - you have to build circuits.
This kind of circuit has many uses - it's not just to make lights blink.
I'll show you some other ways we use these same components to create very different effects in tomorrow's email. Look out for it!
Keep On Soldering!
