Has anyone used the Devantec Compass with the Handyboard? We've used this for several years and all experience has been negative. The conclusions have always...
I haven't used the Devantec compass specifically, but I suspect the electronics, servos and motors of the typical robot are a pretty hostile environment for...
What is the code to turn a digital output on and off? I have a Handyboard with the expansion board. I am also using interactive C to program the bot....
Your IC should have a manual accessible from the application window. In the Handyboard Specific functions you will find set_digital_out(n) to raise the output...
Gleason sells a USB version of the "serint" board -- see http:// gleasonresearch.com/prod.php?sku=HB-USB-INT. It uses the same USB- serial chip that's in many...
I haven't used the PG2033 with the Handyboard, but I have used the Analog Devices ADXL203 2 axis accelerometer and the ADXRS150 gyro. both are 0 to 5 VDC...
If I were trying to do it quick&dirty, I'd start by having a tight loop in a separate process... Read a digital pin to get the pulse... calculate how long from...
I recently purchased a HandyBoard and a motor for a project that I am working on. The motor is rated at 9 volts, and it runs well off of a 9 volt battery. When...
Does anyone know the relation between the sensor's rotation, input signal, and output signal? There's a "high level" RC-related description on the acroname...
... the motor driver chip on the handyboard is only rated to 1 amp. what current rating is your motor? Most motors need a good 30-40% of their rated power to...
I would guess that the lock router is not be met you need one or two thing to happen 1. a 100 uf to start the motor 2. up voltage about two time to start,...
Thanks for your reply. I think that the current is the problem. I don't know the current rating of the motor, but running off the battery it appears to be...
If all you care about is torque, gear it down. I've had some success driving the motor and geartrain from a $10 cordless drill off the handyboard It was a...
It is a shame there are only two TIC ports, it ends up a "choose one" between encoders, sonar and PCM. I will stick with the analog output devices I think. Jim...
I'm having a problem with my 2-d character array. This is my code: char can_tag[9][10]; can_tag[0][]={'0', '4', '1', '5', 'E', 'A', '1', '9', '7', '6'}; This...
I assume this is IC. IC has limitations over standard (or non standard) C. You should use strings to alter your character arrays. The characters in brackets...
I'm trying to pass an array in IC. It tells me I have an error in the passing format. Here is the code for those interested: void main() { int i,j,k=0; float...
Axel, In IC and C typically, if you use the "pointer to" (*) in a function prototype you need to use the "address of" (&) when you call the function. so to...
Hi there, HandyBoard community Since I haven't used them for years but dislike throwing away equipment in working order... Is anybody interested in 2 little...
... doesn't work that way. see http://www.java2s.com/Tutorial/C/0140__Array/TwoDimensionalarraysandpointers.htm for code that works. (beware of line wrap...
... you only need a motor start capacitor for ac induction motors. DC brushed don't need them at all, although a 1-10nF between the inputs and one from each...
... The IR reciever takes up the third one. I've modified my board to make this available for sonar as I'm not using IR. The other two are connected to an...
Hi, I'm having an odd problem with my handyboard. After sitting over the summer, the board does not run on battery power at all. I replaced the batteries...

Lets try to isolate the problem... Break out the multimeter, switch on the board, unplugged and post the following measurements: Voltage between ground and Pin...
... This sounds like your board has a short circuit or something. Mine takes about 20mA when running, and around 70mA with all the leds on. you would have to...
