The car runs on 6.4V battery. It is all wheel drive car - all four wheels turn when throttle is pushed to drive forward or backward. There are two motors that allow to achieve this, one is located at the front of the car and the other one is at the back of the car. These two motors work fine and there is no issue with the the forward and backward movement. The problem is that the steering wheel o...
I need an IoT app to be developed. I have pH, humidity, TDS sensors and an arduino kit. I would like to build an IoT app to monitor quality of water at 4 intervals every day. Once the values are in these values need to be matched with drinking water standard to determine if it is safe to drink the water or not. I would like to collect this data from multiple places and aggregate it on to a map.

Hi, I have software for microcontroller PIC32MX340512H which reads data from A/D converter MCP3424 via I2C bus. The program only works properly if MCP3424 measures a negative value. In this case, PIC32MX340512H displays the correct value. If MCP3424 measures a positive value (voltage), PIC32MX340512H will show an incorrect value. For example: if I connect -1.5V voltage to MCP3424, then PIC32 wil...
I'm working on a prototype for a project and I need to source a circular LCD/OLED (or similar) countdown display timer - see the attached rough sketch. The timer must only countdown days automatically, not hours, minutes or seconds, and be operated by a battery that you would get in a digital wristwatch or car key fob. It needs to be simple and basic in its functionality. If I want to set t...
