Tasks for the week
Problems generated
- connecting the components
- generating a code for the motor to work using the Arduino Uno
- Making a simple block diagram
All the components were segregated. The Arduino was placed at the centre and a motor was connected to one of its pin. In order to check the functioning of the motor, a simple code was uploaded to the Arduino.
The motor worked perfectly and we added a delay of five seconds. The motor spun for a while and stopped for five seconds and the cycle continued.
To ensure that there would not be any negative voltage development that would destroy the Arduino, we tried to put in a diode and a resistor in series with the motor. Any negative current would not be allowed to go back to the Arduino since the diode is forward biased.
The figure shown below is the simple block diagram for the circuit constructed above. A one kilo-ohm resistor was used in series with a diode.

Problems generated
- The motor was rated at 5V, but takes about 4V. When the resistor and diode was connected, the motor was not working
- Resistance value was too high, since it was draining voltage
- With just small resistance, motor worked but with low power as the voltage drop was low across it
