So I wanted to make an RC car without using an arduino microcontroller. So I have bought HT12 Encoders and Decoders as well as these RF Modules (https://www.amazon.com/UCEC-XY-MK-5V-Transmitter-Receiver-Raspberry/dp/B017AYH5G0). The problem is that the receiver doesn't work properly when there is a load such as a motor. My questions is how to get Static Current for the receiver to work properly even if there are two motors running.
I have used many capacitors in parallel to the power supply to smooth out voltage drop when both motors run, which helps a lot but it's still far from perfect. The receiver still takes awhile to get up and running properly in order to receive information. In some cases it might take a 2-3 seconds for the receiver to start working maybe 5.
I use an L293D to drive the motors and there are PNP transistors since the Decoder outputs one when no buttons are pressed. In this schematic the receiver and L293D are powered individually but the same problem exists.
Sorry in advance for my schematic drawing skills, if you have any advice on that, then it would be greatly appreciated.
