I just finished connecting this circuit together. I wanted to connect all the components (nodemcu, servo motor, and solenoid) parallel to the battery, the solenoid and the servo motor will be activated every 5 hours with half a second difference between the activation signal (this will be handled through the code). I connected a 14ohm resistor to the VIN pin to the nodemcu to lower the voltage from 12V to 5V, same for the servo motor as I connected 6ohm resistor to lower the voltage supplied to the servo motor from 12V to 6V.
I'm not sure about some stuff in this circuit :
1- The connection of the components being actually parallel or not, if not please show me the right connection
2-The value of the resistors I connected to each component, I ohms law to calculate the resistance needed.
3-The solenoid needs 2A to operate and I connected nodemcu parallel to it which needs (0.5A) to operate which will be operating all the time and a servo motor that needs a 1A to operate ( the servo motor will be operating at certain time as stated before). My question here does this connection will provide the solenoid the needed current?
Assume the components used are :
1. Battery Lithium-ion Super Rechargeable Battery Pack (12V, 3000mAh)
2. JF-0826B Push Action Type Electric Linear Solenoid 12Vdc,2A
3. Servo motor (6V,1A)
4. Micro-controller (5V,1A)
Note: the circuit is provided in the attachment to this post.
Thanks in advance!
