Note: Due to inventory packaging methods, you may receive more components than required for some products.
Step 1 - Review Components
First you need to check that you have all your parts and tools with the list provided on-site. The only parts that are not included are a
9V battery and wire.
You may have noticed that your IR phototransistor has 2 pins and the schematic shows 3, I will explain how to wire this in the next step.
Step 2 - Construct Circuit
Construct the provided schematic on the mini breadboard, place wires according to the diagram.
Your IR phototransistor has 2 pins and the schematic shows 3, in order to wire this phototransistor the 1k resistor must connect between
pin 2 on the 555 and negative. The phototransistor should be connected between pin 2 and positive 5V from the regulator. No harm will
result if it is placed backwards, but it must be the correct orientation. (Some experimentation will be required when the circuit is powered
up)
When building make sure to use the 330Ohm resistor provided in series (inline) with all 3 of the LEDs so they do not burn out. The
schematic says "optional" because the LEDs I used were rated for higher voltages, the green-red provided are around 2.3V. When
building the circuit, your red led should attach to pin 3 on the 4017IC as that is the '0' output or the line that represents the circuit being
off.
Step 3 - Troubleshooting Common Problems
-Most likely culprit is the IR receiver just flip its orientation and/or try a different remote control
-Check that your ICs are plugged into your breadboard the correct direction (notch pointing upward)
-Check 9V battery levels with multimeter or battery tester if you own one
