Do you have a 3D printer?
Interested in getting prints done, but have no printer?
Let's help each other printing more stuff :)
There may be a 3D printer or someone who'd like to pay for a print close to you..
AKA LMR IoT (Internet of Things) Data Service
Some days ago I saw in sparkfun news this particular one about their new Data Service (https://www.sparkfun.com/news/1527).After that I asked Frits and Matt if we could host something similar on LMR's servers.
In a robot my friend and I are building we are using 2 Parallax HB-25 Motor Controllers to control 2 motors.The problem I am having is making the motor brake (as in freeze robot from moving).
The other day I was trying to reprogram my old bot's line follower and I think I have a CNY70 (http://www.vishay.com/docs/83751/cny70.pdf) that is fried.The line follower schematics is http://www.adrirobot.it/robot_deagostini/line_follower/line_follower.htm (Fascicolo n°49) and the program I used is described in Fascicolo n°57The problem is that 1 of the CNY's in the program is always showing that is has a line under it even if it has none. The others work fine. Is there a way to check if the CNY's receiver part is fried?
