Another solution to this which is easier but more expensive is to use the output of the motor driver chip to drive solid state relays. You need the relays that use 5 volts for control and that will switch DC. The relays I use have flyback diodes in (...) (27 years ago, 9-Apr-99, to lugnet.robotics.handyboard)

(...) Stacking the chips is doable but you will toast them when you get near their current limit. An easier solution is to use the TI chips to drive power transistors that are acting as voltage followers. This lets them take the current. (...) (27 years ago, 9-Apr-99, to lugnet.robotics.handyboard)

| | Increasing current output to motors on HandyBoard

I am looking to drive a radioshack motor off my HB. Its rated at 9V - 18V. It claims that at maximum efficiency it will draw 1.98 Amps. My HB uses the TI sn754410ne motor controller and is rated only up to 1 amp. If i replace this unit with a L293b (...) (27 years ago, 9-Apr-99, to lugnet.robotics.handyboard)

(...) I use both and infrared ranging sensor and sonar. I have them both mounted on rotating bases. If you plan to do some serious work with your application, then you might find this approach a little difficult. The reason is that if your robot is (...)

Hi, Just a quick question...What would be most effective ? An array of sensors (IR or sonar), or a single sensor on a continuously rotating base (assume 1 rotation every 2 secs...) ? Could someone here explain me the main functional differences of (...) (27 years ago, 9-Apr-99, to lugnet.robotics.handyboard)
