I’ve applied as it is, and found it undersensitive also I was too angry to try and tweak it. As I type I prepare myself to try and implement an hardware solution… fetches hammer
I’m not sure what the Tiny13
I’m not sure what the Tiny13 can do but my PICAXE 08M2 is able to use the sensor in a digital fashion. The whole circuit uses 3.3V and with the IR LED consuming 50mA @1.25V it will trigger a digital low when my finger gets around 12mm away. I use the same circuit that kariloy posted. For me R1 is 47ohm and R2 is 10K.
good to know. Will try this
good to know. Will try this with an Attiny when I have time.
