I think we should add a step between #2 and #3 (referred to as New #3) and we need to edit a step and add a new bit of info.

New #3 Connecting the sensor and pHAT
Collect 4 male-to-female jumper wires. On the small green board, identify the labels TXD, RXD, GND, and VCC.
(This sentence needed editing on the notebook) Insert the male ends of the wires into the corresponding locations on the breadboard.

• Connect the male end of the green wire into "e4" associated with TXD (transmit).
• Connect the male end of the blue wire into "e5" associated with RXD (receive).
• Connect the male end of the black wire into "e7" associated with GND (ground).
• Connect the male end of the red wire into "e8" associated with VCC.
• RXD means "to receive" and TXD means "to transmit." This creates a two way communication between a sensor and the pHAT.

USE SAME IMAGE AS IN THE NOTEBOOK.

#4 Connect the breadboard to the pHAT

• Connect the female end of the green wire (from TXD) to the 15/RXI on the pHAT. Your pm sensor can now transmit information and the pHAT receives this information.
• Connect the female end of the blue wire (from RXD) to the 14/TXO on the pHAT. Your pHAT can now transmit information and the pm sensor receives this information.
• Connect the female end of the black wire (from GND) to the GND on the pHAT. Your sensor is no grounded.
• Connect the female end of the red wire (from VCC) to 5V on the pHAT. Your sensor now has power.
• RXD means "to receive" and TXD means "to transmit." Now that you have connected a TXD with an RXI/RXD, your pHAT and pm sensor can communicate with each other.

#5 Should be done.
