How can I improve the stability and sensor placement for my line-following robot?

Hey! We built a robot with wheels and we are doing line follower using 3 black/white sensors to detect a black line. We place the sensor in front of the robot The problem is that the robot is a bit too large for the line, making it hard to stay on track. Its movements are also unstable and sometimes veers off.
Do you have tips on stabilizing movement or optimizing sensor placement?...

Testing ESP32-CAM

I just got an ESP32-CAM from a friend, but he's not sure if it's working properly. I'm testing it using the Arduino IDE with the example camera code. I’ve wired the ESP32-CAM to an Arduino as the programmer. The code uploads successfully, but I gett this error in the serial monitor:

E (396) quad_psram: PSRAM ID read error 0xffffffff, PSRAM chip not found or not supported

How to Optimize Energy Calculations for STM32 Energy Meter Without Overloading Interrupts?

Hello team, so I have been working on an energy meter for some time using stm32f103c8t6 as my controller, zmct103 current transformer for measuring AC current and then using LM324 op-amp in differential mode to measure ac voltage. I have been able to get data with ac load, but my readings(adc readings) and calculations(energy calculation) are done inside interupt. I know the interrupt is meant to be short, is there a better way to handle calculations? I will appreciate your insights. here is t...
