I will be connecting to my arduino nano and the speed controllerĭo i pick one as a power supply or do i need to connect both and if so which way aroundĪnd the speed controller will be on 9-13Vdc as the battery drains That will determine what direction you need to go, but I am suspecting that you need a different motor controller, one that can take digital commands (I2C perhaps).īut i need some help as the product data sheet doesn't make much sense to me. I don't think you specified what motor you are using, or what you are trying to control. I think the first thing that you need to determine is what your motor actually needs. I had trouble getting my 555 to go above 20KHZ, the output voltage dropped. Your motor might be more demanding than a simple computer fan, hence a 555 to produce the higher PWM rate. The whole point of the 555 is to produce the PWM, which the arduino can handle just fine (the frequency is not as has as the fan motor wants, but for most projects it is okay). I know this part would work with the 555, but it seems like the wrong way to go about it. It's a bit of a high end part, very high resolution, and little expensive: AD5292BRUZ-100-RL7, My current project makes use of a digital pot that would handle the voltage range. But in your case the 555 is running on 10v, and digital pots that work at that voltage are harder to find. I believe I found the range to be limited, or tricky to get right. I did use a digital pot in place of the analog pot. I built a circuit like that once to control fan speed. Ill attach a similar circuit that i think it is but im not sure.Īny one know how can i replace or control this I did a little more searching and discovered that there is a 555 ic timer for the pwm to the transistors. The two wires red and black are an on off switch The group of three wires makes sense, the red and black are a mystery to me. If that really is a double stacked pot you are going to have trouble replacing the pot with an Arduino without understanding why there are two pots. Is there a switch built into the pot? You already have a on off switch. The red and black wires from the pot are not making sense to me. I don't understand why the motor controller uses a double stacked pot. Switching noise will effect the Arduino, and maybe even kill it. I would recommend using a separate power supply for the motor controller. I assume that the red board shown in your rough schematic is a DAC, which feeds the opamp. Sorry no idea what a digital pot is but will google it now
