![]() They are ‘all’ easy to work with and Arduino has several example codes. There is information on scaling and documentation in the dht11 humidity sensor post I just replied to so I won’t repeat it here.įYI - the LED part in Fritzing has color selection with includes IR Led’s.īasically, for choices to sense the obstacle, you may be interested in:Įach works and uses somewhat similar interface and code (either On/Off pulses or signal voltage (such as to Arduino Analog pins):Ī light emitter, a light receiver and Resistors and Caps as needed to tune it for the ambient (and usage) lighting.Īmbient, Flashlight and Laser light is also an emitter, thus, needing only a receiver such as LDR. ![]() When I finish some other part creation I can correct what I see is wrong or you can do it as you choose. ![]() The PCB hole sizes are a little large (.1 headers are usually 0.038in holes, yours are a bit bigger than 0.04). In schematic I generally prefer the layout match the pinout in breadboard so the connection is obvious but it is your choice. Things that aren’t quite right but won’t break things: connectors should start from pin 0 not pin1 and be contiguous (this does break things in pin number display, I didn’t look closely enough to see if the pins are contiguous or not). Breadboard is missing connectors for the IoRef connector and that connector is missing from pcb. ![]() The main problem is that the bus configuration in the fzp file is incorrect, a number of the pins don’t exist (which may mean that others are bused in correctly). ![]()
