As an absolute beginner in electronics I was wondering about a few things. Will IR proximity sensors be affected by IR LED lamps? This because I am thinking about adding one to the lazybee (just for playing arround with it) but I would also like to have some IR led's for nightvision (the cam can see IR light).
I already ordered the Ping sensor but where can I mount it on the bot? For example, can I mount it 5cm from the edge of the bot or would that make it "see" an object (the bot itself in this case). Or can I mount it on a little pole so it looks "over" the bot. I'll probably mount it to the front anyway but was just wondering how the signal spreads and returns.
On the resistors, I got a few and one of them has a bit of the colormarkings and covering missing (like a small piece of clay that came off). Can I still use that or is it destroyed?
• The IR sensors may be confused by the camera’s IR LEDs, but you can easily control them to have only one operating at a time. Many IR sensor modules have quite good filtering built into them, so you may not find this a problem at all, even if both sets of IR are running at the same time. Trial and error is really your best option here.
• Sonar sensors like the PING))) can detect objects in quite a wide cone spreading out from the unit, but they tend to miss anything that is angled so as not to reflect the sound back to them. Once again trial and error is key, but if the surface of the body in front of the sensor is smooth and flat then you’re unlikely to receive much interference.
• Resistors are simple and tough parts. If you can only see more of the coating material underneath where it is damaged then the resistor will be totally fine. If you can see some wire or other material where the coating is broken, use a multimeter to verify that the resistance value is still as expected. Also if the coating has been compromised you’ll have to make sure that the exposed area doesn’t come into contact with other conductive parts as it may no longer be insulated.
