Need help in Obstacle Avoiding Robot
July 29, 2019 - 6:28pm

hey. i was following your project https://circuitdigest.com/microcontroller-projects/arduino-obstacle-avoding-robot 

everything i have done by following each and every step but still i am having some problem with the running the project. Actually the project is misbehaving. 

Sometimes it works a bit fine but some time it goes to random direction. also some times the one motor works and other dont and vice versa. i have checked the connections too but still it is not happening. 

can someone tell me what is the problem. i have used same components as you guys have used. and code is also correct.

check power supply
July 29, 2019 - 6:35pm

hi. i may not guess anything without looking at the project image or every wiring. but still i will give you one suggestion to look for power. my reason behind saying to check power is because you mentioned sometime it behaves random and one of the motor doesnt work sometime. Even, i was having a similar problem when i used a lower rated power supply than required. 
i would suggest to check for the current consumption of the circuit. also do check if your power supply is able to provide enough current your project need. 
i really feel that this is a power issue. it is possible that your power supply is not providing enough current. so please try to change the power supply and try to use higher current rated power supply such as atleast 1A or 2A. 
do let me know if solves this problem.

High Power Rating Power Source Selection
May 9, 2020 - 1:18pm

There might be issue with the power source, you installed for powering up modules, motors, center controller, sensors etc. As per you, the robot is misbehaving like its motors are sometimes working and sometimes not. The motor needs more currents as compared with other modules/parts used in the robot development, for that purpose, you need to use a voltage source of high power rating and also you can do so attach separate power sourced for modules, controllers and motors and must join the ground terminals of all the sources together. Here I would like to recommend you to visit the SSLA for getting better assistance from technical support team of this platform.
