A quick and very accessible method for the measurement of acceleration due to gravity is presented. The experimental set-up employs a smartphone ambient light sensor as the motion timer for measuring the period of a simple pendulum. This allowed us to obtain an experimental value, 9.72 + 0.05 m s-2, for the gravitational acceleration which is in good agreement with the local theoretical value of 9.78 m s-2. © 2018 IOP Publishing Ltd.
