Blue Marble Security Enterprise assisted the local Boy Scouts on Tuesday November 27th, 2018, as they participated in a heart rate monitor soldering event. The event is used to teach the basics of electrical engineering components in an interactive and effective manner. The heart rate monitor, once soldered with correct connections, will cause the LEDs to light and with the use of the sensor the LEDs will blink with the operator’s heart rate. Around seventeen boy scouts ranging in the middle school age participated in the event with seven Blue Marble Security members as well as their advisor who monitored and assisted in the lab.
The focus of the heart rate monitor lab is to introduce the basic concepts of electric engineering to those with little experience. Some of the concepts learned are how the color bands on resistors correspond to the resistor’s value, the polarity of diodes, and why it is important to place them correctly. However, the focus of the lab was to make effective through hole soldering connections. Scouts who were unsure about the process got a quick demo from an Outreach team member. All the members got portions of their boards populated with components within the time limit, with a few getting the boards completed and tested. All the boy scouts will get to take a heart rate monitor board home after the Outreach members troubleshoot and finish up some of the boards. The boy scouts had a wonderful time, and learned a new valuable skill.
