You can use the Solar: bit Solar Battery for micro:bit in your classroom to teach students about renewable energy, sustainability, and basic electronics in an engaging, hands-on way. This innovative solar battery allows students to power their Micro: bit projects using solar energy, helping them understand the principles of solar power and its applications in everyday life. As students experiment with the Solar: bit Solar Battery for micro:bit, they develop critical thinking and problem-solving skills while learning how to design and implement projects that harness renewable energy sources. The Solar:bit Solar Battery for micro:bit also encourages collaboration, as students can work together to create projects, share insights, and explore ways to optimize their use of solar power, enhancing communication and teamwork skills. This practical tool not only makes learning about science and technology fun and interactive but also inspires students to think critically about sustainability and their role in protecting the environment.
You can create a simple program on the micro:bit to measure the battery voltage using a jumper wire.
Connect a jumper from the Battery Voltage Monitor pin on the Solar Battery to the P0 input on the micro:bit.
Create a program that will loop on analog read P0 and printout the results. The reading will be between 0 and approximately 400. For example a battery voltage of 4.27 volts will give 1.78 volts at the battery monitor terminal. ( 4.27 ÷ 2.4 = 1.78) and a value of 391 in the analog read.
