Revision as of 07:20, 19 June 2014
Two Arduinos will connect to each other through hardware serial. One is the display and maybe wifi. The other monitors temperatures, throttle, etc. and sends data to the motor controller
Arduino I
This is a repurposing if John's old temperature logger. 2 7-segment LED digits and a wifi module. It also has a 1-wire Dallas Semi temperature module but reading from the module with the Dallas Semi library causes hiccups in the main loop.
Arduino II
| a0 | analog throttle in (3 pin) |
| a1 | analog current in (connector shared with batt voltage: 3 pin) |
| a2 | batt voltage (connector shared with analog current in: 3 pin) |
| a3 | temp 1 (3 pin) |
| a4 | temp 2 (3 pin) |
| a5 | steering pot (3 pin) |
| d0 | comm with Arduino I |
| d1 | comm with Arduino I |
| d2 | |
| d3 | PWM1 (2 pin) |
| d4 | |
| d5 | PWM1 smooth (2 pin) |
| d6 | PWM2 smooth (2 pin) |
| d7 | brake 1 (2 pin) |
| d8 | brake 2 (2 pin) |
| d9 | |
| d10 | |
| d11 | PWM2 (2 pin - wires) |
| d12 | |
| d13 | debug LED |
Test Backup Motor Controller
Test to see if it cuts off at low power and how it reacts to PWM as its input for throttle:
need:
- 1 battery
- wires for battery
- power supply
- motor and wiring
- oscilloscope
- arduino with .1uF and 100K and 10K and 1K (for filtering pwm output if needed)
