Hi all, I am currently running my first Arduino project in which it uses a 16x2 LCD, a DS1307 RTC along other things powered by 5V. I am also using a peristaltic pump that connects to the voltage in and is connected to a battery pack that supplies 9V as well as a 5V 1 channel relay module. However when it is all plugged in, the voltage regulator gets extremely hot and the board switches off. This is the pump section of the circuit, is there anything I need to do so this damn thing can function?! Thanks,
Pump VCC --> NC on relay module
Pump GND -->GND on breadboard/arduino board
Relay Common --> Voltage In
Relay VCC --> 5V
Relay GND --> GND on breadboard/arduino board
S on relay --> pin 13
9V battery pack goes into VDC input
Welcome to the forum! From your word puzzle the motor is getting power from the arduino. A schematic would be a big help to all of us, not a frizzy thing they are never complete. Your pictures are interesting but do not help much. Rule 1 observe all voltages. #2 A power supply an Arduino Is NOT. You will get this to work. Remember the contacts of the relay are completely isolated from the Arduino. You can use a 12V battery, connect one to the relay, the other to the pump. The second lead of the pump goes to the relay, this will keep the Arduino from frying.
Hey all, Thanks for the advice.. I have drawn up a schematic of the project. Please note that connections made via VCC, GND, A4 and A5 are done through the use of a breadboard. I am still an amateur and the schematic is not the best. Thanks.
