Very Low-Level DC Motor Control Systems

Greetings! I am looking for a system for controlling 12V DC motors which allows for me to directly program voltage control via duty cycle. The most common shields on the market have built-in speed-setting control systems, but I would like one which enables control as low-level as shutting the voltage on and off at 12V to enable power via duty cycle. Preferably, this system would have enough ports to supply 3 or 4 DC motors with rated current around 1A and stall current at around 3A. Please advis...

Sim module + Arduino cloud

I want to remote an esp32 remotely and i think ill buy some sim module for that. can i use that to access Arduino cloud so i can use the nice ui?

L293D driver Shield and ESC with Arduino uno r3

I am building a project where i have to use both esc 30A(for bldc motor) and an L293D driver shield(for 4 n20 6v 60 rpm motors). Since the driver shield is stacked upon the Arduino uno, and all the pwm pins are used, how do i connect esc?

Upgradable connections?

I have a circuit board of an rc plane, which i had to open (of course). I want to not only put it back, but also be able to remove the connections and test them on a breadboard or something similar. The circuit board is unlabelled, but i know what everything does. There are two motors, a battery connector and two LED's connected to the same + & -. Images are attached. If there nothing such, what are those battery connectors called?...

DHT11 Humidity sensor not reading.

I am using a keyestudio DHT11 humidity sensor. I have checked the wiring multiple times, so I think it is correct. The error that it gives me switches randomly between 16,12 and 16,16. I have attached a photo of the arduino and where the wires are connected.
