Regardless, if any of you are brave/stupid enough to follow this guide, (I'm joking, it works fine, but check for yourself) here is how you can make your own thrifty throttle for a third of the price or less.īefore you attempt this you need to learn/have some programming knowledge unless you want to copy and paste my code(at your own risk), be able to connect wires, a little perseverance, and some experience with the dark arts ) well, lets just say many (nearly all) of my independent project ended up in smoke or smoked at one point, and, consequently, they played it safe and bought one. My team did end up buying a thrifty throttle because. Hence, I bought myself an arduino and made myself a servo controller under 10 dollars. there was no way I (technically the team)was paying 30 dollars for something a $3 arduino and a decent potentiometer could do.

For some of you it is probably worth the money to avoid the trouble an buy it, but I enjoy these projects as well as saving money, and I wanted to get into arduino, so I made my own version of the thrifty throttle.Īll the thrifty throttle is is a simple pwm generator in which you can adjust the duty cycle/ the length of each pulse. Yes, I am well aware I am being a cheap***.

It is quite ironic something so overpriced has 'thrifty' in its name. When I searched online to buy a replacement I was surprised to find that the price tag on andymark was 30 dollars. Recently, our high schools frc (first robotics challenge) teams thrifty throttle went bad, getting extremely hot when plugged into a power source. I know this will work with talons, talon srs, talon srxes, victor 888s, victor sps, jaguars, sparks, standard servos, most, if not all, escs, and probably more!

Īlso, I can't guarantee my code will work with you servo/esc/motor controller, but chances are it will. If you want a deeper understanding of this project click. so my scooter never stops.Before I start, I already made a guide for this, but in retrospect, it seems overly complicated and overwhelming for those who want to simply make one, so here is simpler, more concise version. I thing the throttle sends from 0,8 to 5v. When I plug the throttle replacing the potenciometer (just pluging same pins) the motor wont be on zero. Then I replace the 4,5v batteries connections to GND and analog +5v of my Arduino.

It increases the motor rotation, indicating it works.

Then I took 3 1,5v batteries in series (4,5v) and tested on pwm controller: With default connections (36v batteries connected, motor connected and default potenciometer connect and running on middle velocity I pluged the negative of 4,5v batteries on red of potenciometer and softly put the positive on the middle pin of potenciometer. Tested with a multimeter and with some adjusts it works great: outs 0 to 5v 'correctly' Then I bought a bigger pwm controller like the one you using, but still without success to drive it from Arduino.įirst I plug the scooter throttle (same of e-bikes) to my Arduino Uno, read the parameters in analog pin and convert to 0-255 analog write. I bought this pwm controller and fried it with some tests. How do I hook up the arduino to the pins on the motorcontroller that would've normally be hooked up to the potentiometer to do the speed control remotely.Īny help would be greatly apprectiated! I'm fairly new to electronics so I'm sorry if these are noob questions. On the poFrom googling I've seen that a digital potentiometer might be an option, but I don't really have the time to order that in time, because we're approaching the deadline for the project.

The on/off switch is also in the pot-meter, but I've figured out how to replace that.

I know that I somehow have to use PWM and a 100K resistor because of the impedance. I've figured out which cable is V+(red), Vout(yellow) and ground(black), that was fairly obvious. I can't seem to figure out how to replace the potentiometer with arduino control. The thing is, it has to be remotecontrolled, we're doing this through an arduino. We're using this controller for speed control. So I'm controlling a fairly heavy motor for a school project and I've got the motor control to work at this point.
