Wiring to a Microcontoller:
Wiring to a Microcontoller:
Basic Wiring Layout
Basic Wiring Layout
VIN
Accepts 3.25V - 5V, (or up to 12V for a short time)
GND
Acccepts 0V, (ie: Ground)
CNTRL
Accepts 0V - 5V
0V - 1.2V is a LOW signal
the plunger will move to the retract position
1.7V - 5V is a HIGH signal
the plunger will move to the forwards position
Step 1 Wiring Actuator to the Breadboard:
Step 1 Wiring Actuator to the Breadboard:
VIN
Attach a Red or White wire to the VIN pin of the actuator
Connect the other end to Red (+) rail of the breadboard
GND
Attach a Blue or Black wire to the GND pin of the actuator
Connect the other end to Blue (-) rail of the breadboard
CNTRL
Attach a third color wire to the CNTRL pin of the actuator
Step 2 Connecting the Power Adapter:
Step 2 Connecting the Power Adapter:
Do Not Wire With The Power Supply Plugged In
Positive Terminal
Find the terminal which has the plus (+) symbol
Loosen the screw, insert a Red or White wire, then tighten the screw to hold it in place
Connect the other end of the wire to the same Red (+) rail of the breadboard as VIN
Negative Terminal
Find the terminal which has the minus (-) symbol
Loosen the screw, insert a Blue or Black wire, then tighten the screw to hold it in place
Connect the other end of the wire to the same Blue (-) rail of the breadboard as GND
Be aware, incorrect wiring here may damage the actuator
Step 3 Attaching Microcontoller:
Step 3 Attaching Microcontoller:
If the Microcontroller doesn't yet have header pins soldered
do so now
If you have never done this before here are examples:
Placing the Microcontroller
Place the Microcontroller in the center as pictured
This avoids two pins from being on the same rail, which would cause a short
(if you only solder one group of header pins this is not an issue)
VIN
Attach a Red or White wire to the pin labeled 5V of the microcontoller
Connect the other end to Red (+) rail of the breadboard
GND
Attach a Blue or Black wire to the GND pin of the microcontroller
Connect the other end to Blue (-) rail of the breadboard
CNTRL
Take the unconnected CNTRL wire and connect to any pin labeled with a number on the microcontroller
Now you may connect the power supply, if the actuator does not move the plunger to retract position, or the ESP32 does not show power, disconnect power immediately and recheck wiring
When programming the microcontroller please disconnect VIN from the microcontroller before programming
(This avoids the actuator from drawing power while programming)
