having got the stepper motor running the next thing to do is to send signals to the arduino chip (the ATMega 168) over bluetooth. for an arduino intro see this post). the bluetooth chip i picked up is a […]
stepper: two (synchronous) steppers
The mount will need two stepper motors and I want them to both move at the same time – I don’t want to ‘move all the azimuth steps’ and then ‘move all the altitude steps’. And they also need to accelerate / decelerate as in the last post. So, again, a bit of amendment was […]
stepper: accelerating with new arduino library
Next up, a way of accelerating and decelerating a stepper motor. The mount can’t just whack in to top speed it needs to start off slow and speed up. So the idea is to be able to set the min speed, max speed, and the number of steps taken to accelerate. The result looks something […]
stepper: arduino driven motor
So, first step (excuse the pun) is to get the arduino to drive a stepper motor. ultimately there will obviously be two (one for the altitude axis, the other for the azimuth). i got both these steppers from […]
Arduino – first light…
So this is the ‘brains’ of the binocular mirror mount. or at least this is the gadget used to programme those brains. it’s an arduino (pronounced: “aard-ween-oh”), as if you hadn’t guessed. The idea is to programme the chip to receive commands from a laptop (via bluetooth) and then move the two stepper motors accordingly. in time, it might get a bit more advanced – for example having direct ‘user control’ via a keypad as well as receiving instructions from a laptop.
