I am creating a security system that triggers a 18M2 to count down from 10 to 0 on a (https://www.sparkfun.com/search/results?term=com-11644) and activates an 08M2. There is a 315Mhz receiver (http://www.adafruit.com/product/1096) as part of the system such that if the keyfob is pressed the...

I started a thread a couple weeks ago regarding this issue but don't know where it went . The good news is that I have a working RTC circuit after finally figuring out that the $FF and "?" were because of a low battery problem. I have searched this forum and Google for ways to sync the 08m2...

I am trying to build a countdown timer using a 08m2 and the 4 digit 7 segment display here https://learn.sparkfun.com/tutorials/using-opensegment The code here is just trying to get the display to count up but no luck. I would post a schematic if I knew how to create one like I have seen on...

In the thread "Daily Lights" there is mentioned a one button synchronization to set the ds-1307. Could you point me to the circuit diagram and code for this please?

I am trying to get my LCD, https://www.sparkfun.com/products/9568 , to leave a blinking cursor at the position in the attached code. I have searched this forum and Google but with no luck, at least that I could understand. Any help would be appreciated.

Greetings all, I recently got my LCD-09568 from Sparkfun and had it working fine until I did "something", I know not what and now the character blocks are on all the time. I have read some posts regarding this LCD display but have been unable to make those pixel boxes "invisible" like they...

I am attempting to run a simple schematic using a picaxe 18m without success. The code compiles in the program editor but I get a syntax error in VSM. If I comment out the #picaxe 18m2 then the error becomes the second file attached. If I change picaxe 18m2 to picaxe 18m then I also get the...

My AXE027 USB programming cable is giving me problems. I have to push it, pull it, twist it to get it to make contact on the mini jack end. I convinced myself there was a bad connection in the cable so I took it apart by removing the "shroud" from the jack end. There are 3 wires, orange...

I have created a 555 circuit in VSM but am having a problem with the output. I have tried to figure out how to get the circuit schematic out of VSM and into this post but have had no success. Does anyone have a simple step process for accomplishing this task?:confused: Thanks, Berny

I am getting some errors from SPICE when trying to run the simulation. Where can I find the "meaning" of these errors? I tried to cut and paste them here but was unsuccessful. I also tried to use Alt printscreen without success. I tried ISIS help searching for "error" and "message" which...

I cannot seem to understand how to connect elements between sheets. I have read the HELP several times and just don't get it:confused: Can someone give me a "very" simple process to make this work. In my circuit the connection is simply supplying a + voltage and a ground. Update...

I get a syntax error on the following two code statements using a 40x2: pwmout c.1,249,400 pwmout c.2,249,400 The error is - Error: Invalid pwmout pin (use C.5)! According to the pinout for a 40x2 this should work. It was working with a 28x2. What am I doing wrong?:confused:

Perhaps I am not using the software correctly. I have a 28x2 using 2 Pulsin pins to get signals from a RC reciever yet there is only one generic parameter in the simulation program. How can I get the simulation program to allow 2 generic inputs so I can see if my PWM equations are working as...

I pulled the following from a 2004 thread: "The method you are after is the same as that used by robots for obstacle avoidance. It is called "vector forces". Draw your robot's outline on a peice of paper and consider the forces that your motor/wheels apply individually. Draw these as...

I purchased the 08m starter kit and wired it up. I am using my regulated supply set at 5 volts and switched to monitor amps. When I attach the board to my PC and turn on the 5 volt supply the amp meter jumps to well over 1 amp. This is without the picaxe in place. Is this normal?:confused: I...
