Pro Mini does not have 0, 1 and 5V. How to do please?
For my Nano 5V it says "4:25: fatal error: VirtualWire.h: No such file or directory"
How come it doesn't compile Nano? Does Mini Pro use different code?
But with wall power instead of solar
Did you have any luck with this? I've done some research. https://forum.arduino.cc/index.php?topic=425890.0
Can you link me to some info about doing this using wall power and having the phone/load run operational at the same time please? Here's my research efforts thus far. https://forum.arduino.cc/index.php?topic=425890.0
Oh yes, I see the night time part of the charging cycle in the graph - that's a problem. How do I make the thing forget that it's day or night?
I know this is anti-planet, but it a self preservation home security type deal, so it is pro-safety.
Hi Deba. I need to make this circuit using wall power instead of solar power, much like a mobile phone charger. I need to have about 800 mA (peak) plus a bit of current for charging. Seems like this contraption of yours will work for my purposes. There are plenty of mobile phone charger builds on the internet, but none with load sharing! The load I have is a Nano, a servo and 2 white LEDs. Any help please?
Note: the circuit is working of wall or battery power, I just want it to have power management and charging, with wall and battery as alternate inputs and battery and load circuit as outputs. You can see my fruity endeavours so far at https://forum.arduino.cc/index.php?topic=425890.0
I don't understand the maximum current output of the MCP73831 chip. Could I output about 700 mA to my circuit and say 100 mA to my battery?
This would work with an MPU-6050?
I have had good luck with this setup using the HC-SR501 but found the HC-SR505 (the mini version) unreliable, either overactive or not working at all. I have tried multiple units and have not tried to modify the code/wiring. Someone PLEASE help me to use the mini!
It won't work probably because my motor is 12V. Now I need to try a boost converter or find another way. I think I would use PWM via a 555-timer if I had one. Any thoughts? In update, I now have managed PWM via L298N motor driver and a potentiometer. In order to make the speed go really slowly and constant it seems I need to use either a step motor instead of a DC motor or use speed feedback on the DC motor. Just my understanding so far.
